I've been following Mr. Molina's artistic career for a couple of years, and am glad to see he now has a book published. This is a stupendous book for the beginner to intermediate paper crafter, since the designs increase in difficulty. However, advanced paper crafters may be inspired to create new designs and find innovative applications to this old world craft. This is NOT a book for young children. The use of sharp blades, scoring tools, and protractors would make it dangerous and frustrating. Artistically gifted 10 year and older children may be able to use it with supervision - great for teaching geometrical concepts. So, purchase the book, get your basic paper crafting tools, and escape to a world of creative entertainment.
