Every so often you learn of a new concept that is so simple you wonder why it was not thought of before. This paper is about such a case: the exploration of D-Forms, where new three dimensional forms are created by joining the edges of two flat surfaces that have the same length of perimeter. This then leads onto other developable surfaces, all of which offer a host of ideas for sculpture.
