I used to have a light grey fleece design wall and it worked well. I liked it especially when I was working with blocks with white fabric as you could see the design well. I recently bought automobile liner fabric from JoAnn's because I heard Eleanor Burns recommend it. My first attempt with the auto liner didn't work well...regular fabric stuck but once there were seams in the fabric it would fall off. I didn't have the auto liner fabric stretched tightly on the insulation board so I am going to experiment with that and using the other side of the fabric. If that doesn't work I will go back to batting or fleece. If anyone has any hints on the auto liner please let me know...ditto if I have to give up on using it as a design wall what do I do with it????
