Although I think this is a great book, It could do with a lot more explanation of "how" things are done. Diagrams are very good but most are more of a picture as opposed to proper explanations. A good command of origami is required to complete many of the exercises. I can see many long evenings ahead!!!
At over 500 pages, this is a big book with lots of models, but none of them are original, and many are of the 'front and back joined together in the middle' multipart variety common in the sixties and seventies. Disappointingly, none of the diagrams are attributed to their original creators. The book is colourful, and the diagrams clear and easy to follow. If you like dinosaur models, you'll love this !
