There is evidence that a knitting technique using shortened rows has been used since the 16th century for shaping the heel of socks. This master thesis created at the Lucerne College of Art and Design investigates the question why the same technique was not also used to make seamless outerwear. Based on an elaborate investigation of the mathematics of knitting techniques, it can be demonstrated that the ancient craft technique is suitable for the production of contemporary and sustainable clothing. In the practical part of the study, the theoretical findings have been checked and verified, and illustrated in five prototype articles of clothing. Following on from the MA project a fashion collection was finally created.
