Origami paper

The only real requirement of the folding medium is that it must be able to hold a crease, but should ideally also be thinner than regular paper for convenience when multiple folds over the same small paper area are required (e.g. such as would be the case if creating an origami bird's "legs", "feet", and "beak").

Some washi does not hold a sharp fold due to the extremely long and thick fibers of the paper.

Chiyogami refers to Japanese hand-screened decorative kozo washi / paper consisting of repetitive patterns.

Originally the design was applied to handmade kozo paper with wood blocks, but today most chiyogami is produced with silkscreen techniques.

The brightly printed chino-gami of Edo (Tokyo) and Kyoto and the crisp strength of newly laid kozo paper were fully utilized.
