Many designers, from jewellers to architects, use folding techniques to make three-dimensional forms from two-dimensional sheets of fabric, cardboard, plastic, metal and other materials. This unique handbook explains key folding techniques, such as pleated surfaces, curved folding and crumpling. It has been updated with a new chapter covering some lesser-known techniques, suggesting yet more creative possibilities. The techniques are accompanied by clear step-by-step drawings, specially commissioned photography and ten new instructional videos.
