I have nerve damage and have the same problem. I do suggest getting the shower grip at Wal-Mart, you'll find it back in pharmacy where they have the disabled aids. These have a stronger suction than the ones made for quilting rulers. I tried the sandpaper dots but found the grit of the sandpaper wasn't big enough to actually hold. I went to Lowe's and found adhesive sandpaper with a larger grit that holds pretty good. Between these two items, I can pretty much anything I want.
