Mark, you know those refigerator magnets you get from just about everyone? The ones the bank sends you with a calendar, or the local parts store with their hours and phone number on them.... If I had stickers like you do, I would apply them over those frig magnets (I actually do this alot with photos). I do it with car show stickers and do-dads too.

They are long lasting, and moveable.
