I did 2 bungee cords hanging from 2 eye screws in the ceiling and tied a clamp at both ends...works great, very little expense..the clamps I ordered from a quilting site...they are for the ends of the long arm quilting set up, to clamp the sides of the quilt to keep taute,,I tried to find clamps at several stores, but they were too hard to open..these that I got are fantastic...keeps a king size quilt up at the back of my sit down quilting machine...good luck with yours..l
