Natural Dyeing and Tapestry Weaving with Omar Chavez. Omar is a master weaver and natural dyer from Teotitlan Del Valle, in Oaxaca, Mexico. I met Omar last May when I was lucky to get to spend a week learning tapestry weaving from Omar and his parents Fe and Lola in their studio in Teotitlan. I was so inspired by the stunning creativity and the sheer amount of planning and hard work that goes into creating each of their tapestries.
