In this follow-up to his first book, Folding Polyhedra , Alexander Heinz introduces eight more paper-folding models. Most of these models are easy to assemble from a combination of folded triangles, squares, pentagons, and hexagons, which are assembled in a symmetrical modular way, allowing you to create more than 60 forms by using and combining the different folded paper models. The models presented in this book use a mathematical geometric folding technique that Alexander Heinz developed himself. The models all have the same edge length, allowing every one of them to fit together edge to edge and corner to corner and making folding and combining the models easy. The projects are for all ages! They look very complex but are actually very simple to make. Once readers have mastered the models and learned to assemble the forms, they can use these techniques to create unique and colorful paper sculptures and ornamental designs.
