If one takes the narrowest possible dictionary definition of the term, a "crease pattern," or CP, is nothing more than a set of lines that is a representation of some subset of folds in an origami shape, real or imagined. But it can be, is, more; the deeper question is, what does a crease pattern represent to some person?
In 1999, I was commissioned by Brailsford Studio (San Diego, California) to create four origami bronzes as part of the public art component of the Downtown Transit Mall project commissioned by the City of Santa Monica and the Big Blue Bus.
I am often asked what kind of paper to use for origami. There is no single answer; it depends on what you're folding. On this page, I'll talk a little bit about the most common types of paper for origami and my own experiences with them.
