I have a frame my husband built from a kit. He did all the wood work and the way it's made, it rolls the quilt up as you quilt. When he built it, I swore I would never do anything larger than a twin, so that's its capacity, right now. However, it could easily be converted to accommodate a much larger quilt. Because my husband built it before he died, and because it is so convenient (the quilt surface can be tilted to any angle you desire) I treasure it greatly.
