The Cojolya Association is a non-profit weaving cooperative and museum run by and for Tz'utujil Maya women, dedicated to preserving and promoting the town's textile traditions. The small museum explains the history of backstrap loom weaving in Santiago Atitlán and demonstrates the techniques, with weavers often working on site.
The shop attached to the museum sells high-quality woven pieces at transparent, fair prices that go directly to the weavers — the garments, bags, and wall hangings here are more expensive than the market but are the genuine article, made with traditional techniques and natural dyes where possible. This is consistently rated among the most worthwhile purchases available at Lake Atitlán.
