This book is probably the single reason modular origami continues to gain new fans. Pick up this book, and fold the beginning boxes... In no time, you'll be hooked and want to fold every box, shortly after that you'll want to experiment with different papers/colors/patterns/etc. This book, (while fundamentally simple..the charm of modular...) has a wealth of great boxes. The best part is, when you are done, the boxes can be used as gifts, or gift boxes, and look great for any celebration. I highly recommend this book to all origami fans, but not too people who are only interested in finding difficult models.
