I have many quilt tops my grandmother made in the 1930's from used material. Very fragile. I backed some of them with muslin, no batting, and carefully knotted them with cotton thread at the intersections of seams. I added a sleeve to the backing material at the top and hung on a wooden dowel. All of the weight of the quilt is on the muslin, not the quilt top. I change them out frequently and they are hung in a spot that gets no direct sunlight.
