ABSTRACT

A tuck-based branch is repeated as many times as necessary. The result is this mountain range-like shape. The fold lines alternate between mountains and valleys at the edge of the paper. The tips after branching have alternate mountains and valleys from the outermost line. Tucking of a part of the paper, like the inside-reverse-fold, is applicable also to multiple curves on a crease pattern. The single mountain fold line branches into three at the point where the inside-reverse-fold starts. The newly branched two outer lines are mountain folds. The original fold line changes from mountain to valley fold after the branch point. With some fold lines added outside, the whole piece is finished beautifully.
