This paper continues the refinement of Richard Roth's taxonomy of isonemal weaving designs through types 11–32 of the 39 in order to solve three problems for those designs: which designs exist in various sizes, which prefabrics can be doubled and remain isonemal, and which can be halved and remain isonemal. 1. Introduction Except for a short list of interesting exceptions, Richard Roth [1993] has classified isonemal periodic prefabric designs into 39 infinite sets. The first 10 have reflection… CONTINUE READING
