If you don't have this book in your collection yet, you need to get it. If you already have it, you should pick it up and re-read it, as you'll surely find something new every time!

This book is filled with theory and diagrams of every genre of origami in existence. We have masks, Animals of every kind, realistic and more abstract, modular and geometric shapes, as well as discussions about mathematical, aesthetic and design aspects of origami, introduction to crease patterns, and more. Every chapter is brimming with ideas and challenges.

In fact, this book is so big, that when the Hebrew version was published in Israel, it was split into 3 separate volumes!

I believe this book to be one of the most important origami books ever to be published.
