I found this vintage vegetable puzzle at a thrift store. I thought it was charming so I give it new life as refrigerator magnets. They are a perfect accent for my kitchen. How-2: keep an eye out for a vintage puzzle of your liking. Alternatively, use a puzzle that your child has outgrown. These puzzles turned frig magnets will make a fun keepsakes. Use a hot-glue gun to attach strong magnets to the back of each piece.
