I made some glass marble travel magnets. This is a really, really simple craft that can yield some fun results and serve as a gift or replacement to the free car insurance or portrait of your uncle Ted's family magnet that currently adorns your refrigerator door. You can use any small picture as a background (magazine clippings, photos, decorative paper) and then just trace out a circle, glue it to the back of a flat glass marble, attach a magnet, and you're done! The hardest step in the process for me was finding the larger sized clear glass marbles, but if you can't find them in a craft store, you can buy them online. I chose to print out Google Maps locations from some cities I've traveled to recently.
