In this book, well-known origami artist and prolific author John Montroll provides a wealth of origami folding instructions for beautiful three-dimensional geometric shapes. He goes beyond the average origami book and describes design techniques and mathematical methods behind the creation of these models, all of which are folded from a single, square, uncut sheet of paper. Practicing with Montroll’s models and then following his suggestions and techniques will inspire you to design your own origami polyhedra!
