This book is an amazing assortment of creative origami models, but it is most definitely NOT for a novice of origami. I've been folding paper for more than 2 decades now, and have found a few models in this book really challenging. Like most instructions in books by Montroll, there are some steps which appear vague, but once you crack the mystery, then you'll understand that there really isn't any better way for the diagrams to be done. The models in this book are a bit more advanced than in Animal Origami by Montroll, and fairly comparable to many of the designs in "the Complete Book of Origami" by Lang.
If you are an intermediate level artist, this book is sure to present some frustrations, but offers so much more satisfaction in the long run.
