I also use a flannel backed table cloth, sometime two together I purchased from Wal Mart. I use them on the floor, as I don't have a good wall space. I lay out by blocks or fab. pieces and usually take a digital pic. of it then, move them around and retake pics. I can always delete the pics. and not have to print them out. When I don't want to lose the design and have to quit working on it, I just roll the table cloth(s) up with the blocks left on them and then they are rady for the next time I get to work on it. This works great for me, especially if I want to take it to my quilting club meetings and get others opinions for lay outs if I'm at a loss or something.
