Double Weave is an ancient technique widely practiced by pre-Columbian cultures that fell out of use since the Spanish invasion and was eventually forgotten by nearly all modern weavers of Peru. It is an extremely difficult technique in which two planes of textile are woven simultaneously, intersecting to form patterns on both sides while creating a two-layered cloth. The movement of threads between the layers allows complex patterns and interesting textures. The very nature of the technique points to the notion of complementarity, or the balanced interchange of dual elements. This concept is evident in other applications of Andean textile arts, and much of indigenous social organization has been based on the principle of reciprocity.
This technique had been lost to time until Tinkuy 2013, where CTTC weavers worked alongside Jennifer Moore, an expert doubleweave weaver from the United States, to learn and recover this forgotten knowledge; an ancient art form from their own culture that they were able to revive. A few years later, letting the weavers practice and gain more confidence with the complex technique, the Center organized a competition in 2016 with the ten weaving associations. As a result, the weavers presented highly creative and sophisticated doubleweave pieces showing their extraordinary efforts to master the recently recovered technique. The CTTC weavers have continued to master this technique since then, expanding their creativity being inspired by their ancestors' textiles.
