I saw this book a few days ago and then read the reviews which completely put me off. However, yesterday I was in a bookshop and flicked through it and it's not as bad as I thought it was going to be after reading the amazon reviews.
This series of books 'encylopedia of...' is a pretty good series and I have a couple of them already - 'Encyclopedia of papercrafts' is particularly good, but what needs to be understood is that it is an encyclopedia, which for me has always meant 'reference book' rather than practical 'how-to' guide. It contains an introduction to origami, some information about paper types, folding and then the basic folding techniques. There is also a handy glossary at the back and a gallery of 28 pages of 'Origami from around the world' to show what is possible by using the same basic folds and a little imagination. This is the reference aspect of the book and is designed to inspire you.
Having said that, this book does contain 32 step by step projects at what they call 'beginner', 'intermediate' and 'challenging' levels. Remember that depending on who you talk to or what you read, there are either only two basic folds or six basic folds! Everything you will do will be based on those folds regardless of what level you are working at or what you are trying to create.
At beginner level - the boxes are very useful as gift boxes, at intermediate level - the skeletal cube is interesting, the bear is cute, and the peacock is impressive, and at the challenging level, I really do like the double cube, and the flower.
So yeah, a bit of reference, an inspiration gallery and some practical how-to projects makes this a pretty good all-round book to have in your collection.
