Great Idea sewmary. I'm a big fan of the dollar store
. I use the dollar shelf liner to keep my pedals in place. I also use the "shape cut" rulers. Never giving THOSE up. Perfect every time no slip. Ive sprayed fabric adhesive. Every works pretty well-but I'm going to give the shelf liner a whirl. Also the non-slip mats for underneath area rugs. It's pretty much like the shelf liner but bigger.
