Modular Sonobe Origami contains instructions on how to fold sonobe units into 140 different shapes. Instructions include a color coded unit system which displays how each unit must be folded to be assembled and what space it occupies in the final shape. Each shape also includes a modular diagram which divides the shape into smaller shapes to make the shape more understandable. Shapes can be assembled using the original sonobe unit included in the instructions or any other style of sonobe unit which can be found online or in other modular origami books.
