Symbols used in Origami

As origami grew increasingly complex and specialized, distinct notations were developed to describe the folds involved.  The method used almost universally to denote folds in origami is the Yoshizawa-Randlett System.  This sytem has distinct notations for folds, movements and repetitions.  This helps the artist to follow the instructions in a design book.

Following are some links to the methods of notations.
