Ruth, When I started making my design wall I was using a sticky-back core board and scraps of flannel. I was just picking flannel that fit the board and sticking it on and nailing it to the wall. I'm sure I've got fabric grains and naps running everywhich way! No, I don't think it matters.
When I first read your note I was thinking, *napping on the walls? I can't sleep vertical!* Who's warped! :lol: No napping on my walls.
