In the early 1990s, the Association for the Ecological Development of the Sierra Madre Occidental, A.C., coordinated the construction of a weaving workshop for the manufacture of high-quality cotton muslin cloth in Nueva Colonia in the community of Santa Catarina Cuexcomatitlán, Tuapurie. In this letter, financing is requested from the director of ADESMO, Juan Negrín, for work related to the construction of the weaving workshop's installations.
