I don't have a wall either, but they work great on the living room floor. When things are just right, I can fold them up following the row lines, then unfold one row at a time to sew. I often store things for awhile and when I get back to them the blocks are just as I left them, ready to be sewn. I love those flannel backed cloths. K-Mart had some really big ones for $1.00 in their after Christmas sale. But they aren't all that expensive when they are not on sale. I use mine on a queen size bed also when I'm sewing at my son's house. It is so portable. A quilting essential.
