This Lap Cloth is a high contrast model and features a black fabric on one side and a white fabric on the other. This allows the spinner to see their fiber in the "drafting zone" while they spin. Simply use the dark side for light colored fibers and the light side for dark colored fibers. The cloth is made of 2 layers of sturdy 6-7 oz. Twill fabric (cotton/poly blend) which is washable.
