My DH bought 4 pieces of PVC pipe (about 3/4") & 4 elbows & I bought some cheap flannel quilt backing at walmart & made sleeves on all 4 sides & I have about a 6' square design wall for about $20. light weight, easy to move & big enough for what I need. I just lean it against the wall where ever I want to use it.

For a design wall when I go to classes or working other places, I have a large flat flannel sheet and use the painter's tape. I use alot of tape but will try the pin idea next time. Why didn't I think of that.

Looking at the one you saw my question is how stiff is the surface? Do you have to support the back when you put up your fabric or block? Otherwise a good idea if you have the money for it.

I just use the back side of a plastic flannel backed tablecloth. Works fine and is cheap, cheap, cheap.

this is the one my mother just got for in the trailer to take with her travelling. it looks like a nice one.
