I went to the dollar store and purchased a flannel back table covering for a large table (paid only $1.00) then brought it home and nailed it on my wall behind my sewing machine from the edge of the ceiling down flannel side up. I not only use it as a design wall but sometimes put pictures on it etc. it lays flat on the wall so I never have to move it as it is not in my way and is directly behind my sewing machine so I can actually reach across and put a block on it. Holds large blocks and small blocks and if I need to I can use pins if need be. In case your wondering do the pins ever go into the wall.........No because I pass the pin only on the table cloth like when you are pinning a pattern on fabric. It works great for me and was very inexpensive. Hope this helps.
