I hate to say this, but I have no idea what a Grace frame is. I've only been exposed to the 1x2 strips of wood/fabric stapled and held together by C-clamp frames. Oh yeah, they were held up at the corners by whatever stand someone had welded together for the "frame" owner. Starting to sound more and more primitive. I think I helped staple some fabric back on one once. It was a big deal to get to "turn" the quilt. That meant it was getting smaller and would take up less space.
