The RPS Studio 10 x 10 ft. Cloth Muslin Photography Background (Choma Key Blue) is designed to be a lower cost alternative to RPS Studio standard muslin material. Although these value backgrounds have a smaller thread count they still have a weight and stiffness that is expected of a good muslin material. As with their other muslin backgrounds, three sides are hemmed and there is a standard 3 inch top pocket for the crossbar. And, of course, they are washable.
