Computer-assisted crafting is one type of software that can prove relevant for non-industrial crafting communities, such as Santa Clara del Cobre in Mexico. We developed artisanal pattern CAD software, based on the Adolfo Best Maugard drawing technique (Best Maugard, 1923, 1927), to teach Mexican-style drawing to children. Developed with sculptors James Metcalf and Ana Pellicier and the artisans of Santa Clara, this software enabled users to create primitive graphic motifs and combine them into patterns. This environment provided alternate ways of exploring variations in the creation of motifs and their arrangement into patterns. The software was developed using a vector drawing program, Sketch, as a platform. It was designed not to replace traditional ways of crafting but instead to offer new ways to explore the creation and combination of traditional patterns.
