These rugs are handwoven using a 100% wool weft and a 100% cotton warp. The weft is everything you see and feel on the rug except the fringe. The warp is the skeleton of the rug. We use cotton on the warp to guard against possible moth damage. Many of our rugs are designed in our locations in New Mexico and Arizona, with the actual weaving being done in skilled adult weaver's homes in India. There are no dyes used in this rug. All colors are natural sheep colors. The grey wool comes from spinning white wool with black wool. The warp (fringe) is 100% natural cotton.
