This happens a lot in my house: puzzle pieces go missing. Then what? The kids don't like the puzzle and won't play with it. But since it's missing pieces you can't really sell it. It seems wasteful to throw the whole thing away. I LOVE what Amanda from Crafts by Amanda did the solve this dilemma: and she ended up with TWO awesome projects from the whole thing!
