I'm redoing my quilt cave and including a barn door design wall, which means my current design wall (insulated foam board with flannel covering it) is up for grabs. I see that you're in Michigan; I'm in northwest Ohio. If you're in southern Michigan you are welcome to my design wall and all it will cost you is gas. PM me if you want it!

PS I don't know how much the board was to make it since my husband picked it up for me, but it's been worth it's weight in gold!
