The creativity and natural beauty of origami have their roots in geometry. The 20 projects in this kit cover a variety of different types of unusual geometric shapes and demonstrate many principles that offer a deeper understanding of origami as an art form. Create shapes including tetrahedrons, icosahedrons, and an impossible triangle inspired by the art of M. C. Escher. You'll even learn how to take an octagon apart to create a square. Every project is crafted with no scissors or glue, using the custom-designed paper included in this kit.
