The cooperative ATMA has been created to promote an ancient knowledge used in the creation of Hanbel products.

The women weave on both traditional vertical looms and horizontal European looms. Using local wool spun by hand, they weave Amazigh designs into hanbels, zarbias and other types of traditional rugs. They use modern and finer materials in European looms to produce jellaba fabric, scarves and other products.

Around one hundred female weavers of different ages, all members of the cooperative ATMA are involved throughout the whole production process: research, cleaning, carding, manual spinning, warping and weaving of the wool.
