The design wall I use, is a large section of picnic tablecloth that I have stapled on and raped around a 1 x 2 piece of wood. I have a hole in each end I hang on nails I put into the wall (and remove when done). The lines on the front show through to the back. The fabric I got from Joann's, but probably available elseware. I do have to take the photos off the wall before I use it.
