There's more than one book that has this title and they share some models but they are different books. This one has a mix of modern and traditional models, each diagrammed and illustrated with photos and drawings, and brief sections on how the various folds in the book are diagrammed and the types of paper needed as well as a page on other ideas for using the models. All of the models are fun and would be easy enough for kids while being fun for adults as well. The 15 models are: * hats * glider * fox family * snapping mouths * snake fangs * big bang * jumping frogs * windmills * beads * star box * bombs away/waterbomb * lily * flapping bird * Christmas tree * star Recommended for ages 6+.
