What You Need:
Clear marbles with flat backs
White craft glue
What to Do:
1. Cut out photos of family or magazine pictures of some of your dad's favorite things (like cars, sports, etc.) that are about the same size as the marbles you're using. If you can't find anything you like in magazines, you may find pictures online that will work and you can print them out on photo paper.
2. Put a thin layer of glue on the front of the picture then press the marble onto the picture. Allow to dry completely.
3. Stick or glue the magnet to the back.
