I have just the right number of pieces left...12 (2 for me to finish as well). I'll have to package Tuesday as my week is pretty full after that, but gotta get those pieces out!
This will be fun.
As to puzzles, also check the toy stores, they usually have wooden puzzles for not to expensive and look through the discounted areas for puzzles. I found wooden ones at Toys R Us in a markdown aisle, flipped the pieces over to the backside, sanded lightly and primed. Did not have to cover up the picture this way (it also made putting it back together easier if the labels fell off).
