I use my old fashioned quilt frame which my MIL used to tie quilts. It' queen sized. I pinned a flannel bed sheet to it. (My DD decided he did not like flannel sheets, so it a used sheet.) I found the blocks did not stick well on it, so was pinning my blocks to the flannel. What a pain.)
Now I bought a can of spray adhesive and lightly sprayed the entire front of it. That works.
