Book excerpt: In Origami Zoo, two of the world's finest paper folders present an exciting collection of original origami animals. Their creatures, ranging from the exotic to the familiar, the elegant to the whimsical, will both inspire the beginner and challenge the most accomplished folder. Choose among the dolphin, penguin, swan, owl, goose, kangaroo, praying mantis, or even the mythical Pegasus or extinct wooly mammoth. Each of these thirty-seven new projects is true origami-folded from a single piece of paper with no cutting or gluing-and is complete with clear step-by-step diagrams, instructions, and a photograph of the finished model. Origami Zoo will challenge and delight anyone with a penchant for creating something wonderful out of (almost) nothing.
