When I go to Wal Mart, I look in the bin where they stick discount fabric. I found a large piece of white flannel! What a find!
I had been to the dollar tree here, and bought a few pkgs of large (pretty) binder clips (like the black ones, but with pretty designs) and I bought some of those hooks that you put on the wall, but can remove easily without damaging the wall (3M). I put 3 of those hooks up there, hung the binder clip handles on the hooks, and clipped the fabric to the clips. Its wonderful. My ceilings are slanted in the sewing room, so I can't have too large a piece. Its perfect for me (a beginner).
I'm on my laptop and my pics are on my desktop but I can post tomorrow when I get back on my desktop. :-) It was simple, easy, and inexpensive! (doesn't get much better than that!)
