I did something similar to BellaBoo. I got a 4 x 8 sheet of insulation board from Lowes and covered it in batting. Then I got cream colored flannel at Walmart that was really wide (maybe 90"??) and wrapped it over the batting and stapled it on the back. The whole thing is really lightweight. I hung it on the wall with 2 long screws that I put through a washer first. One thing I learned is that you can't screw through the flannel; the flannel will wrap around the screw. So poke a hole first for the screw to go through. Have fun - you (and your knees) will love the result.
