Start with 3 colors of clay in equal amounts. Roll each into a long snake that is approximately the same diameter.
Form those snakes around one of the clay cutters to make a rainbow. You can cut the snakes in half first if they are long enough so you can make two earrings from the same pieces.
Slightly press these together then cut off so that they are the same size.
To make tops for your earrings, you can take your scraps and use the same marbling technique above.
Add a hole to each piece with a straight pick.
Once all your earrings are made, bake according to the package directions.
Allow to cool then make into earrings using jump rings, earring posts, and jewelry glue.
