Use photo editing software to size your images to fit your glass marbles; print out using a laserjet or dry ink printer.

Cut out your photo shapes and set aside.

The glass marbles are not completely round, so trace them onto your scrapbook paper pieces and then cut out the shapes just inside the lines.

Use Mod Podge to adhere the face (right side down on the marble). Smooth and allow to dry for 15 - 20 minutes.

Adhere the scrapbook paper (right side down) on to the marble, allow to dry overnight.

Hot glue to the magnets to the back to finish.
