From Bullock Museum’s website:

Hilos de Tradición: Dresses of Mexico is a collaborative exhibition with the Brownsville Historical Association that presents Mexican textiles as living traditions with roots that can be traced back thousands of years to the earliest peoples in Mesoamerica. The tools, patterns, materials, and techniques of crafting these textiles have evolved over the centuries. European influences and modernization have contributed to these changes. But the common thread in all of the textiles is the link they represent between Mexico’s past and present.
