Zig Zag Folds
Definition: Paper folded in zig zag folds has two or more parallel folds, each folding in opposite directions. Because they do not nest (as in Spiral Folds) panels can be the same size.
Also Known As: accordian folds | z folds
Examples: Seen from above, zig zag folds resemble a Z or M or series of zigs and zags.
