State Puzzle Trend?

I'm seeing a trend of fabulous uses for USA puzzle pieces.  You could of course use the ideas for any kind of puzzle, but I have a thing for states.  First I saw these key chains at the Junk Bonanza.
Just drill a hole and attach a key chain!
Then while on a day trip (which I will share with you tomorrow) to Meadowview Barn Sale I found these magnets!
So when you find your puzzles are missing pieces think about what else you can do with them before you toss them!
