But, whatever you patch up, make it solid and strong. Do not try to work at a rickety, shackly apology for a bench that shakes and jumps and sidles all over the room every time you saw or pound or plane. You can probably get all you need in the way of boxes, packing-cases, and such material, at very little or no expense. The illustrations (Figs. 85 and 86) are merely suggestions, for you must use your own ingenuity, according to the materials you can find. Most experienced workmen have often been obliged to work at much worse benches than these, frequently with no bench at all.
Those of the boxes which you do not use whole you should take apart carefully (see Withdrawing Nails). This will add to your supply of nails. Use nails freely in fastening the boxes and boards together and to the wall or floor wherever allowable. A few screws will add much strength.
The bench shown in Fig. 86 calls for one good board for the front of the top.

Some of you live in the crowded parts of the city, in flats or small houses where there is no possible chance for a shop of any kind. Whatever wood-work you can do must be carried on in the kitchen, or some other living-room, where even a small bench may be out of the question. Still you would like to make such small work—model boats, for instance—as can be carried on in such limited quarters. If you are forced to use the kitchen table for a bench, try, for the first thing, to brace or block or screw it to make it steady, for unsteadiness is the greatest hindrance to doing good work at such a bench.
You can fit a good board to the table-top with cleats, and a stop to hold the work (Fig. 87). If you can now get a common iron vise, you can get along quite well for small work, and the board and attachments can be quickly taken off and put away when the table is needed for domestic purposes. You can easily contrive some way to attach wooden pieces or leather or rubber to the inside of the jaws of the vise, to save marring your wood-work. A fairly good bench can often be made from an old table (as a kitchen table) by screwing a plank on top and a board on the front side, and bracing the legs (Fig. 88). The plank should be screwed on from underneath.

If you can get hold of an old bureau or chest of drawers you can arrange a serviceable and compact little "parlour shop" for small work. If you cannot fasten permanent attachments to the bureau, you can fit a removable board (Fig. 87), and you will be equipped for such work as can be suitably done under such circumstances—and that includes quite a long list of small things. The drawers can be fitted with compartments and trays, according to what you have to keep in them and your own ingenuity, but make the arrangement simple. Figs. 89 and 90 are merely suggestions.
The best way to arrange your tools and supplies depends somewhat upon the circumstances, but the main point is to have the most convenient place for each thing and always to keep it in that place when not in use. The first part of this proposition is almost as important as the last. It is nearly as bad as being disorderly to keep the glue-pot in one corner of the shop, the glue in another corner, the glue-brush in the third corner, and the water in the fourth—which is no exaggeration of the way some very orderly people stow away things, and is about equal to the arrangement of the person, of whom you may have heard, who always kept everything in its place and that place the floor! The workshop interior shown in the frontispiece and in Figs. 91 and 92, and the various other illustrations, furnish suggestions which may help you in the arrangement of your shop.
Fig. 91.
Have everything where you can lay your hand on it in the least possible time, the tools used the most the nearest to you, tools that go together, as bit-brace and bits, kept near together. Have all the common tools right within reach, and not put away in chests and out-of-the-way drawers, just because you have seen somebody pack away his tools in a highly polished chest, inlaid with forty kinds of wood, and containing ninety-three separate compartments and trays and seven secret drawers, the whole cornered and strapped and decorated with shining nickel plate! Do not be dazzled by that sort of thing, which is not an evidence of true system and orderliness, but merely shows poor taste and a great lack of appreciation of the value and importance of time. Time may not be exactly money in your case, but it may be even more valuable, and can be spent much better than in running around after tools and supplies, and making ingenious tool-chests. To be practical, five minutes a day saved by having things convenient and in place means about twenty-five hours in a year—which means a boat, a sled, or a lot of Christmas presents. So study out the best arrangement for your particular shop and then keep things in order. When working keep only the tools in actual use lying around on the bench. As soon as you are done with a tool for the operations actually in hand, put it back in place, and so avoid the confused litter seen in so many shops.
Fig. 92.
Hang saws against the wall on pegs, or nails, or at the end of the bench. Hang all tools which you put on the wall well above the bench, to be out of the way.
Lay planes on their sides or ends, for obvious reasons, or arrange a little block to raise one end of the plane slightly from the surface of the bench or shelf. The last way is usually more convenient than to lay the plane on its side or end. Keep planes either at the back of the bench or against the wall, or on a shelf under the front of the bench.
Fig. 93.
Such tools as squares, bit-braces, and the like are usually most accessible on the wall, in some such arrangement as shown in the frontispiece. A convenient way to arrange such tools as chisels, gouges, and the like, is to keep them in racks either against the wall or fastened to the back edge of the bench, according to circumstances. Keep each tool in a particular place in the rack and you will soon learn to reach for it instinctively without any waste of time.
Fig. 94.
Bits can be kept in a drawer or box, care being taken to arrange them in racks or between partitions, or they can be stuck on end in the racks at the back of the bench. A good way is to stick each bit point downwards in a hole bored by itself. Various forms of tool-racks, which you can easily arrange for yourself, are suggested in Fig. 93.
Fig. 95.
Fig. 96.
Fig. 94 shows a rack to fit on the back of the bench, an excellent way, in common use with movable benches. Get a board, say 3" or 4" wide and the length of the bench, a strip from ¼" to ½" thick, perhaps 1" wide, and the length of the bench, and a strip ½" thick, perhaps 1" wide, and perhaps two thirds of the length of the bench. Saw from this last strip a number of blocks from 1" to 2" long. Arrange these along the top edge of the board, according to the kinds and sizes of the tools, as shown in Fig. 95. Then lay the long strip on them (Fig. 96) and nail it through each block with wire nails long enough to reach perhaps two thirds through the large strip. You can put this rack together by first nailing at each end. Then all the intermediate blocks can easily be fitted in place and nailed one at a time. The whole can then be screwed to the back of the bench so that the tools will be at the back (Fig. 94). You can make part of this rack solid and bore small holes of various sizes for bits, gimlets, nail-sets, and such tools, which would drop through the larger spaces. Good metal tool-racks and-holders can be bought, but the home-made ones answer every purpose.
Fig. 97.
Fig. 98.
The large steel square can be hung very well with nails or small blocks of wood bevelled toward the wall (Fig. 97). For the try-square nail a rectangular block against the wall (Fig. 98). A smaller block nailed in front will hold another smaller square. Slanting saw-kerfs in another block will hold scrapers (Fig. 99). Always keep your oil-stones in shallow boxes for protection from dirt. You can easily make one, or cut a depression in a block to fit the stone, with another for a cover. Fasten one end of your strop to a strip of thin board (Fig. 100) with a hole by which to hang it. You can then use the strop lying flat on the board or loose in your hand for curved edges.
Fig. 99.
Fig. 100.
Do not keep nails and screws after the usual domestic fashion—all sizes, shapes, and kinds mixed up promiscuously with a lot of metal rubbish and carpet tacks in some old box or pail. You will waste twice as much time trying to find what you want as it takes to keep them in separate boxes, or trays with divisions. A good way is to use either small open boxes or flat open boxes with divisions, so that they can be reached as conveniently as possible. Tin boxes or canisters or pails (of various sizes), such as cocoa, coffee, lard, and such substances come in, are good. Put labels on them and arrange them neatly in some accessible place, as on a shelf over or at the end of your bench, or in a cupboard or a drawer.
Keep scrap boxes for old pieces of metal (iron, brass, etc., in separate boxes), so that you will know just where to look for what you want. Keep a brush for cleaning off the bench and the work, a broom for the floor, and a box for shavings, sawdust, and chips.
Any workman is liable to cut or pound his fingers, so have a small box in a handy place with some neatly rolled bandages of cloth, some surgeon's plaster, and a bottle of witch-hazel (hamamelis) or some other preparation for cuts or bruises. In case of a bruise, or if you pound your nail, put your finger at once in as hot water as you can bear. Do not, as is often done, put glue on a cut, because of danger of infection, for the glue is made, as you know, from animal refuse and is not always in a pure state.
Do not leave oily rags lying around in your shop to get wadded into a pile in some corner and catch fire by spontaneous combustion. Either put them in the stove at once, or, if you want to keep a few, put them in a stone jar or covered tin box. Matches should always be kept in a covered metal box in a wood-working shop.
Lay in a supply of strips, waste junks, and odd pieces of wood, which you can usually get at any shop at little or no expense. They will be very useful until you accumulate a stock from your own work.
Chopping-Block.—A good solid chopping-block is a great convenience, so watch for a chance to get a section of a tree, which you can often do when one is felled.
Straight-Edge.—You should have at least one; two are very useful—one two or three feet long and another five or six feet long. Making them is simply a matter of skill in planing. When you can plane well enough make some yourself of well seasoned, straight-grained white pine or mahogany, or other wood which holds its shape well. Until you can do it accurately, however, get some good workman to make one, for a straight-edge that cannot be relied on is really worse than none at all. (See Straight-edge.)
Bench-Hook.—The bench-hook (Fig. 101) is very useful to hold work firmly for sawing, planing, etc., and also saves some marring of the bench-top. Before beginning work read carefully Marking, Rule, Square, Saw, and Plane, in Part V., and look up any other references.
Fig. 101.
Fig. 102.
Fig. 103.
Fig. 104.
Take a board, say 15" long x 6" wide, of some good wood like white pine, making both ends square. The surface should be planed true (see Truing Surfaces). With the square mark the line a b (Fig. 102) accurately, say 2" (or the width of any blocks you may already have for the end cleats) from each end, but on opposite sides. The cleats c (Fig. 101) must be true and the edges square. Bore the holes in the cleats with a bit a little larger than the screws (see Boring). Hold the cleats exactly in place at the cross-line a b and start holes in the board with a gimlet or bit a little smaller than the screws. Countersink the holes (see Countersink). Use screws long enough to get a good hold on the board but not long enough to go through it. If board and cleat are each 7/8" thick, 1½" screws will be suitable. Screw one of the middle screws in each cleat firmly to a bearing (see Screws), keeping the cleat as nearly on the line as possible. Adjust each cleat exactly in place, in case it has slipped, hold it firmly, and drive the remaining screws. Before screwing on one of the cleats mark a line around it in the middle with the square, as shown in Fig. 103, marking first across the edge o (against which the work is to be pressed), from that line squaring across the top, and then across the outer edge. After this cleat is screwed on, carefully saw it in two exactly on the line. By letting the saw run in the kerf thus made, you can cut pieces off square. Sometimes one cleat is made shorter, so that you can saw clear through a piece without damage to the bench (Fig. 104). See Mitre-board, page 92. Two bench-hooks are useful for long work.
Horses or Trestles.—These are to lay stock on for marking and sawing, to put large work together on, and are convenient for various uses (Fig. 105).
Fig. 105.
Before beginning work read carefully Marking, Rule, Square, and Saw, in Part V., and look up any other references.
The proper height for your horses, as for the bench, depends somewhat on your own height, and may be anywhere from 18" to 2' 3". Experiment with boxes to find the most convenient height. If too low, you will have to stoop over too much. If too high, it will be awkward to rest your knee on a board, to saw, and to fit work together.
Fig. 106.
Fig. 107.
Fig. 108.
Fig. 109.
If you have a piece of fairly good joist, from 1½" × 3" to 3" × 6", you can use it for the tops of your horses. Saw off two pieces from 2' to 3' long. Mark the best sides for the top. Mark each end like Fig. 106 (showing top and bottom) with the pencil, measuring carefully so that the bevel or slant will be the same for both legs (see Bevel). Holding the work in the vise, with saw alone or saw and chisel remove the pieces marked, so that the end will have the shape shown in Fig. 107. If you use the chisel, look out for the direction of the grain at each corner and cut well outside of the line, until you find which way to push the tool in each case (see Paring, etc.). Trim these cuts as accurately to the lines as you can. Get out eight pieces for legs, of such a length that the horses will be of the height decided on. First make them all of a width, then saw one piece off the right length and mark the others by it—not each new piece by the one last marked. Nail or screw these legs in place with 2" nails or 1¾" screws, keeping the inner edges of the tops of the legs even with the tops of the horses (Fig. 108). See Nailing and Screws, and look out for splitting. Get out the cross-braces of board and saw the ends at a bevel to correspond with the slant intended for the legs. See that the ends of these cross-braces are cut at the same bevel. Use the bevel if you have one. If not, first square each end with the square and pencil, and then measure carefully equal distances on one edge before drawing the slanting lines (Fig. 109). Nail or screw these on (Fig. 110), adjusting the legs to the bevels just cut. Saw or plane off the projecting ends of the legs on top. If you plane, do so both ways to avoid splintering (see Plane).
Fig. 110.
Fig. 111.
Now stand the horses on their legs (Fig. 111). If they should happen to stand firmly and evenly, see first if it is not due to unevenness of the floor. If the floor is true, and they stand steadily in different positions, you can throw up your caps, for you will have beaten the average workman. To make them stand evenly, see Scribing, Winding-sticks, etc., in Part V. Make the tops of the horses as smooth as you can. Scrape them and keep them scraped (see Scraper), for you will be continually dropping glue or varnish on them, to harden and deface your nice, smooth work. Wipe them off as carefully as the bench-top. These easily made horses will answer your purpose for a long time.[18]

Mitre-Box.—Great care is necessary to make an accurate wooden mitre-box (Fig. 116), although the process is simple. Do not make it of spruce or any wood liable to warp or twist. Pine or mahogany is good. Use stock from a middle board if you can (see Chapter III.). A mitre-box can be of any desired size.
Before beginning work read carefully Marking, Rule, Square, Saw, and Plane, and look up any other references.
Fig. 117.
Fig. 118.
A good size is from 1' to 2' long and from 3" to 6" square (inside), according to the work for which it is to be used, and of stock 7/8" thick. The pieces must be prepared with care, so that the edges shall be square and the surfaces true, particularly on the inside, for when the box is put together the sides must be parallel and square throughout with the bottom, on the inside. Test each piece with the square. Use care in screwing the sides to the bottom to keep them exactly in place (see Screws). Nails can be used, but screws are better. Lay out the lines for the sawing from the inside, with the steel square if you have one, or with the end of the tongue of the try-square. Mark the line a on the inside of the side x (Fig. 117), squaring from the bottom. Mark the point b at a distance from a just equal to the distance between the sides. Square a line at this point from the bottom, on the inside as before. Carry this line across to the side y, squaring from the inner surface of the side x, and mark the point c on the inner side of the side y. Also from the point c draw a vertical line on the inside of y corresponding to the line a. Carefully mark the line g h, which will give the mitre. The lines should be laid out from the inside, because it is against the inside surfaces that the pieces to be cut in the mitre-box will bear.
Another way is to square a line m n (Fig. 118) across the top side of the bottom piece, before putting together, and to lay off from one end of this line a point o on the edge, at a distance equal to the width of the bottom, thus fixing the points m, n, and o. Next fasten on the sides, square upright lines on the inside of one side from the point m and on the inside of the other side from the point o. The diagonal line pq (Fig. 119) will represent the mitre.
Fig. 119.
Fig. 120.
The cuts for the saw to run in should be made with a back-saw or a panel-saw. In a similar manner square on the inside two upright lines opposite each other, draw a line across the tops of the sides to meet these lines (squaring from the inside as before), and make a saw-cut, as shown by the middle line in Fig. 116. This will be very useful to saw strips squarely across. You can put buttons on the outside near the lower edge to catch against the front edge of the bench-top if you wish, or use the mitre-box on the bench-hooks when necessary to hold it firmly.
Fig. 121.
A very useful mitre-board for sawing strips, mouldings, and the like, can be made with two short boards, one wider than the other, being sure that the surfaces and edges are true and square (Fig. 120). This can be of any size. A good size is from 1' to 2' long, 6" wide (in all), and of stock ⅞" thick, but it is better to make the narrow piece thicker, perhaps 1¼" or 1¾". Mark the lines first on the bottom of the narrow piece, then on the edges, and lastly on the top, as with the mitre-box just shown, to ensure the lines being at the correct angles with the surfaces against which the wood to be sawed will rest. An excellent plan is to make saw-kerfs for mitres in the cleat of a bench-hook (Fig. 121), in the way just shown.
Fig. 122.
Fig. 123.
Shooting-Board.—This is useful for squaring edges and small surfaces and ends with the plane, and for jointing edges, the plane being pushed forward on its side (see Shooting-board, in Part V.). It can be of any wood which holds its shape well. Clear white pine or mahogany is good. If carelessly made it will be of but little use. The stock must be planed free from winding. Several forms are shown in Figs. 122, 123, and 124.
Fig. 124.
Before beginning work read carefully Marking, Rule, Square, Saw, Plane, in Part V., and look up any other references. The construction is plain (Fig. 122). Approximate dimensions are given, Fig. 122 being made of 7/8" stock, Fig. 123 of ½" and ¼" stock, and Fig. 124 of 7/8" stock. Screw the pieces together from the under side (see Screws). See that the stop or cleat a is put on at right angles to the edge b. Mark the lines for this accurately with knife or chisel. A groove is sometimes cut for this stop, but this is a refinement that is not at all necessary if you do your work well. This board must have a rabbet or groove cut out of the upper piece, as shown, to give room for shavings. In Fig. 123 the top board overlaps the ends of the cleats a trifle, which (with the spaces between the cleats) allows the escape of the shavings. Arrange some way to hold the board firmly on the bench. Care is necessary in using the shooting-board not to plane slices from your left hand. Guides, to attach to the plane to ensure square edges, can be bought and used instead of the shooting-board. Some of them are serviceable, particularly those adjustable at various angles.
Fig. 125.
A mitre shooting-board (Fig. 125) is also useful. It requires to be made with even more care than the board just given, but on the same principle. The angular stop or stops must be fitted to make the angles exactly 45°. A sawed mitre holds glue better than a planed mitre, but sawed mitres often require trimming with the plane to get a perfect fit.
Form for Rounding Sticks.—You will be continually wanting to make sticks eight-sided or round. A form to hold the pieces for planing is a great convenience.
Fig. 126.
Before beginning work read carefully Marking, Gauge, Plane, and Nailing, in Part V., and look up any other references.
Fig. 127.
Fig. 128.
Fig. 129.
Take two strips and plane off (or even chisel or whittle) one corner of each, first gauging lines equidistant from the corner for a guide. Then nail the two strips together, with the bevels facing each other, to make a trough as shown in Fig. 126. Put a screw in one end to push the work against, push the form against the bench-stop or screw it in the vise, put the piece to be "cornered" or rounded in the V-shaped trough, and it will be firmly held with the angle upward. Two or three of these for larger and smaller pieces will be very useful. They are quickly made of waste strips. If you think 2' the right length for one of these forms, for instance, make it a foot or so longer, and after it is made saw off the extra length in one or two pieces, which will serve as an extension for holding a long stick (Fig. 127). If your bench has wooden bench-stops you can make some stops with notches in the top (Fig. 128) for this purpose.
For making pieces tapering, as well as eight-sided or rounding, you have only to modify this idea by planing off the corners in a tapering way (Fig. 129). See Rounding Sticks.
Fig. 130.
Level and Plumb.—Before beginning work read carefully Marking, Rule, Square, Gauge, Saw, and Plane, in Part V.
To make a plumb like Fig. 130, take a piece of straight wood from 3" to 5" wide and 4' or 5' long with the edges straight and parallel. Gauge a line down the middle of the side, exactly parallel to the edges, and cut the notch shown at the bottom. Make a saw-kerf at the upper end of the line and another beside it in which to catch the end of the line, or fasten the line around a nail. (See Plumb.)
Fig. 131.
To make the level shown in Fig. 131, it is essential that the bottom board c d be straight on the lower edge. The two braces a c and a d should be of the same length. The strut a b should be nailed across at the middle of c d and at right angles to it. The essential thing is to have the line a b exactly at right angles to c d, the object of the braces a c and a d being to stiffen the board c d, and to keep the lines a b and c d at right angles to each other. The plumb-line is hung and used as in the case just given, the board c d being used for horizontal work. (See Level.)
Cabinets, etc., for Tools and Supplies.—A tool-chest, though a very convenient (and in fact necessary) thing for a workman who is moving around from place to place or who needs a safe receptacle in which to lock his tools in a factory, is not at all necessary in a private shop, nor half as convenient as to have the tools where they can be more readily reached. It is quite a piece of work to make a good one, and it will be better to defer such a job until you feel the need.
An old case of drawers, or bureau, or cupboard, or some such receptacle, if you can find one, will be useful in your shop. A bureau, in fact, makes a good tool-cabinet or substitute for a tool-chest, but if you keep tools in drawers make compartments, trays, or divisions, else the edge-tools may be damaged, not to speak of the inevitable confusion.
You do not need a tool-cabinet for half a dozen tools, but when they begin to accumulate it is a good thing to have and a good thing to make, if there is occasion to keep your tools locked up or if you have limited room. Otherwise it is just as well to keep the common tools as already shown. A cabinet is fully as useful for miscellaneous articles like brads, hinges, etc., as for tools.
Before beginning work read carefully Marking, Rule, Square, Saw, Plane, Nailing, and Screws, and look up any other references.

Fig. 133.
Perhaps you can find a good box, wide and shallow, all made, or if deep you can saw off part to make it shallow (Fig. 132). This will answer perfectly for a shop. For the house you would of course make a cupboard of new wood. The size must depend on circumstances. Get two boards for doors that will just cover the open side of the box, unless the box cover will do, which is unlikely. If the edges are not good you must allow extra width for jointing. Lay these boards in position and mark the lengths (on the side next the box) by the box itself, not with the square, for the box may not be square. From the lines just made mark the edges with the square, and, with the straight-edge, connect these edge marks by lines on the face sides. Saw off by these lines. Mark the box and each door in some way (Fig. 133), as "top," and "R" (for right) and "L" (for left), or by marks, as X, O, #, etc., to prevent finally putting them on wrong side out or wrong end up, as is very likely to happen if you neglect to mark them.
Fig. 134.
Fig. 135.
Fig. 136.
Now for hinges. The best thing, on account of the weight to be hung on the doors and the poor quality of the wood generally used for boxes, will be iron strap-hinges made for work of this sort, screwed on the outside (Fig. 134). Two will do for each door. Next to this come the common iron hinges. If the sides of the box are thick and firm, three of the common long and narrow kind (Fig. 135) will do for each door. If the sides are thin and flimsy, nail or screw a strip inside of each edge and use wider and shorter hinges (Fig. 136). To fit the hinges, see Hinges. The doors being hung, take them off while fitting up the case. Gauge a pencil line around the outer edge and each end of the inside surface of each door, where it fits against the edge of the box, as a limit beyond which racks or tools must not project or the door will not shut (Fig. 137).
Fig. 137.
Fig. 138.
The fitting up of the cupboard must depend on its size and what and how many tools or supplies are to be kept in it. Shelves you can simply make of the right size and nail into place from the outside, using the rule and square to get them in the right positions. The illustrations are merely suggestions which you can alter or improve upon to suit your particular case. Fig. 138 shows another form, and Fig. 139 a small cabinet with one door, with suggestions for the arrangement of the tools, but the matter of fitting up you must, of course, contrive for yourselves, according to the circumstances. Do not attempt to put full-width drawers into these wide, shallow cabinets, as is often done. It takes an expert to fit drawers that are wide and short (from front to back) and they are not always satisfactory even then. If you wish drawers, either put in a row of narrow ones, or use the simple device described below (Figs. 141 and 142), and shown in Fig. 139. (See Drawers in Part V.)
Fig. 139.
To fasten the doors you can hook one on the inside and put a button (which you can whittle out) on the outside to hold the other. If you wish to lock, hook one door inside and lock the other to it (see Locks). A padlock with staples and iron strap is easier to put on. To make a cupboard of boards instead of using a box, you simply make a box yourself (see Box-making in Part II.) and then proceed as above.
Fig. 140.
Fig. 140 shows a good form of cabinet. Make a tight box, perhaps 2' × 3' × 6" to 9", the sides and ends of 7/8" stock, and the top and bottom (i.e., the front and back of the cabinet) of ½" stock. Saw it open carefully on the line a b c about 2" or 3" from the top or face, according to the thickness of the box, first marking the ends or the sides so that you can finally put them together again in the same positions. When nailing the box together omit all nails which could interfere with the sawing. They can easily be put in afterwards. (See Box-making, in Part II.) Carefully smooth the edges after the saw. Reckless and hasty planing will spoil the joint. Fit two strap-hinges, or three of the common kind. Fit up inside as you wish, and fasten with hasp, padlock, or a lock working on the principle of a chest lock.
All these cabinets must be firmly fastened to the wall, for they will be very heavy when filled. Do not trust to a couple of nails or screws, the way amateurs so often put up shelves and cabinets in the house. A ledge of some sort below is a great help (Fig. 140) to relieve the screws or nails of the weight. If the back is not very strong, do not trust wholly to it, but add cleats outside or inside. If in the house, stout screw-eyes of heavy wire in the sides of the cabinet, through which you can screw to the wall, are good (Fig. 140).
Good shelves can be made by arranging empty boxes one on top of another, or by taking a wide, thin (flat) box and fitting shelves across it, like a bookcase, and then fastening the whole to the wall.
