We received this book/kit this Christmas and excitedly broke into it as a family event. We are three adults with varying levels of education (through post-graduate) and three children to 9 years old. We tried the Giraffe first and were immediately frustrated by the instructions. The pictures are insufficient and the instructions are obscure. It seems the author was attempting to give the shortest description possible and by this effort left out needed information.Independently and as a group we tried to understand his instructions by experimenting for over an hour. The purpose of the book is to eliminate experimentation and teach you how to "do" the work, it fails.I would NOT recommend this book/kit to anyone. There are other books which show and explain origami much better than this one. Working with this book is an exercise in frustration.
