Having been at the beginner level of origami for many years--that is, I follow the ideas in the books and don't create my own--I have at least 30 books on subjects from origami boxes to modular (unit) origami to dollar bill origami. This is one of the best introductions to origami in general. Dollar bills are made of excellent paper with printing on them that helps you get oriented with the diagrams in the book. The projects make great gifts (and tips at restaurants, of course).This book does not introduce you to the variety of "folds" (such as the outside-reverse fold and the rabbit fold) that are the vocabulary of the mainstream origami books, but eases you into the basics (including the inside-reverse fold without labeling it as such). You will enjoy the transition of your ordinary one-dollar bill into these little origami models, which are mostly three-dimensional (many origami books have you sweating and, 47 folds later, ending up with a flat two-dimensional depiction of some insect). Go to other books if this one inspires you to become an origamist. Or just stay here and have fun.When you have folded your masterpiece, origami is fun in that you can unfold it and practice it again until you have it memorized, very useful for when you want to leave a "Dime-In-Ring" as a tip (this project will cost you $1.10--a dollar bill and a dime).I would not simply hand the book to a young child as the projects probably work best with an adult helping those under 10 years old. I suggest that the adult complete the model first before working on it with a child.I recommend getting a bunch of new crisp bills from your bank. Ask the bank when they come in, usually in January. Just in case the US government has any plans to change the pattern on the one-dollar bill, that's another reason to hoard some of the old ones. However, bills that are fairly crisp but not necessarily brand new work very well, and you can find these regularly in change handed to you.Lastly, as commented on already, the humor and the little facts about money are quite entertaining. Typical "Klutz book" excellence.Happy folding.MikePS Another book, also on an origami specialty but also for the serious beginner who wants to produce fun and useable projects is "Wings and Things: Origami That Flies."
