I was struggling to hold a screw with my big hands while starting it with the drill when my wife came in the room and solved my dilemma with Gummy Tack. She worked in an elementary school and apparently this stuff holds schools together. Just put a little ball of it where you want your screw, stick the screw in and get it started and then just pull away the gummy tack before completely tightening the screw. It's amazing stuff.. It sticks enough to hold stuff, but never leaves any marks and never dries out. She keeps a big ball of it stuck inside the junk drawer and when we need some, we just pull off a pinch of it. It sticks, but not permanently, to everything.
