Sorry I don't have much experience with design walls, not much wall space available in my small house and waaay too much animal hair...

So I understand the question/concern better, the batting will be more or less permanent and what you use to stick the fabric to? I can see how that would work. My friends have used flannel or the specialty fabrics.

Edit: I should mention that I have been thinking about covering the back of the door to my sewing room to use as a design wall, it's not much space but the pets aren't allowed in there anyway. I'm going to be making some modern/contemporary quilts that are a departure from my typical traditional approach and could use some help laying them out and/or putting them in sewing order. Currently I use my queen sized bed for such things, but obviously I have demands on the bed that aren't on the back of the door!
