VALLEY FOLD This is the standard fold that creates a “valley” at the base of the fold. It will therefore generally be referred to in diagrams simply as a “fold.”
MOUNTAIN FOLD The opposite of a valley fold, where the fold makes a “mountain” at its apex.
VALLEY FOLD AND UNFOLD A valley fold that is then unfolded to leave a crease.
MOUNTAIN FOLD AND UNFOLD A mountain fold that is then unfolded to leave a crease.
FOLD AND UNFOLD This appears to be the same as the valley fold and unfold, but the arrow is different. This arrow signifies that the fold can be initiated from either side of the paper; the result is the same.
INSIDE-REVERSE FOLD Pressure is applied to the paper along the ridge of the crease, pushing it inside and thus reversing the crease center orientation of the paper.
ENLARGE/REDUCE CIRCLES These encircle an area that will be expanded to show small folds with better detail. When the small folds are completed, the diagram will return to its original size, with no circles.
BOOK-AND-CUPBOARD FOLD AND UNFOLD This is a commonly used reference to describe folding a piece of paper in half and unfolding (book), then folding both outer edges in to the center crease, and unfolding (cupboard). This fold is a prerequisite step in all of the Wire Frames in this book.
WATERBOMB BASE
This base isn’t used in this book, but is useful for illustrating the techniques that follow.
01 Fold diagonals and unfold.
02 Mountain fold halves and unfold.
03 Pushing in the center point, collapse the paper, bringing the two edges of the horizontal mountain fold together.
04 Stages of the collapse in progress.
05 The completed Waterbomb Base.
OPEN-SINK FOLD
01 Start with a Waterbomb Base. Fold the top layers into the center vertical line and unfold.
02 Open out the top of the Waterbomb Base, making mountain creases around all sides of the fold made in the previous step.
03 Invert the point, pressing on the area indicated by the arrow, and begin to bring the pairs of edges back together.
04 In progress.
05 The completed OpenSink fold.
CLOSED-SINK FOLD
01 Start with a Waterbomb Base. Fold the top point to the bottom and unfold.
02 Keeping the front and back layers together, push the point inside, and begin to invert the paper.
03 In progress. Open the edges slightly if needed.
04 In progress.
05 In progress. Begin to close the edges back together.
06 The completed ClosedSink fold.
SQUASH FOLD
01 Start with a Waterbomb Base. Fold the top point to the bottom and unfold.
02 Separate the points’ layers on the bottom, and make both sides of the crease mountain folds.
03 Apply pressure to the ridge on the crease, allowing the layers to separate.
04 In progress.
05 The completed Squash fold.
SWIVEL FOLD
01 Start with a Waterbomb Base. Fold the top point to the bottom and unfold.
02 Fold the top flap on the left into the center as shown, and unfold.
03 Make a new valley crease between the circled areas through the top layer only. (The paper will not lie flat.)
04 Using the mountain fold from step 2 as a guide, swing the edge over to create a new valley crease.
05 In progress.
06 The completed Swivel fold.
CURL These arrows indicate that the paper should be curled where indicated.
ENLARGE/REDUCE These arrows indicate the next step will be shown larger or smaller.
PLEAT SYMBOLS indicate a back-and-forth mountain/valley fold.
ROTATE This symbol signifies that the paper should be rotated the number of degrees indicated in the direction of the arrows.
FLIP OVER This symbol means that the paper should be flipped so that the underside is facing up.
