To make them:
1. Shape some flattened balls from FIMO or Sculpey modeling clay. They should look like small pebbles. (Mine are about 1 inch in diameter, but make whatever size you want.)
2. Bake the little pebbles in your oven until hardened, following the package directions.
3. After they're cool, paint on them with acrylic paint.
4. Hot glue a magnet on the back.
Maybe I'll put some in the shop when I get a little time and see what happens.
