Rather than covering every inch of your sidewalk and driveway and chalk, let kids flex their creative muscles with this outdoor chalkboard. No need to worry about erasers—rain will provide a natural cleaner.
Try this idea: glue (Mod Podge) a photo/picture to the back of a puzzle, one piece at a time and cut out. You'll end up with a double sided puzzle. Or glue pic to front of old puzzle and cut apart for a new one-sided puzzle.
