My son made me a design wall out of soundboard (at Home Depot). He reinforced it on the back with .5 x 2 inch boards. Then I covered it with batting from Wal Mart (first I used the cheap kind in the package, now they don't carry that so on the next one I used the regular $3.90?/yd batting) and it works great. You can stick even the thinest flower pins in the soundboard. Without pins it works only with a lightweight block. The board just rests up against the wall at a slight angle.
