There are two traditional methods for making polyhedra out of paper: polyhedral nets and modular origami.In the net method, the faces of the polyhedron are placed to form an irregular shape on a flat sheet of paper, with some of these faces connected to each other within this shape; it is cut out and folded into the shape of the polyhedron, and the remaining pairs of faces are attached together.
Geometric Origami is a book on the mathematics of paper folding, focusing on the ability to simulate and extend classical straightedge and compass constructions using origami. It was written by Austrian mathematician Robert Geretschläger [ de ] and published by Arbelos Publishing (Shipley, UK) in 2008.

Almost every origami book has basic instructions and a set of folding symbols. The following are books that happen to have detailed explanations of these techniques, and how the techniques are related to each other: David Lister (29 February 2024). "The Origin of Origami Symbols". British Origami Society. Robert J. Lang (1988).
The Miura fold is a form of rigid origami, meaning that the fold can be carried out by a continuous motion in which, at each step, each parallelogram is completely flat. This property allows it to be used to fold surfaces made of rigid materials, making it distinct from the Kresling fold and Yoshimura fold which cannot be rigidly folded and ...
Limp binding of an incunable, made of vellum with broken book clasp of the 15th century. Limp binding is a bookbinding method in which the book has flexible cloth, leather, vellum, or (rarely) paper sides. [1] When the sides of the book are made of vellum, the bookbinding method is also known as limp vellum. [2]
3 ways to fold hand towels: Method 1: round fold. Lay a hand towel on a flat surface. (FYI, you can use any size towel for this method.) Take one corner and fold it away from you.
Robert J. Lang has applied rigid origami to the problem of folding a space telescope. [7] Although paper shopping bags are commonly folded flat and then unfolded open, the standard folding pattern for doing so is not rigid; the sides of the bag bend slightly when it is folded and unfolded. The tension in the paper from this bending causes it to ...
