This book contains diagrams for 20 models created by Jorge Jaramillo that will lead you step by step to the finished model, starting from a square or rectangle; it will show you how to produce the regular polygon from which every model is made. Models range from simple to complex and previous experience in origami is required. All the models are of the geometric kind, a genre for which very few books have been published. It also contains photos of the finished models to guide you with the very few shaping moves that models require.
