Prepare The Clay - Give each child a small amount of polymer clay. Warm and condition the clay with clean hands until it is easy to shape.
Sculpt Your Halloween Design - Shape the clay into a simple ghost, pumpkin, mummy, monster, or other Halloween design. Keep the sculpture relatively flat so it works well as a magnet.
Add Details and Texture - Use coils, small clay pieces, toothpicks, stamps or clay tools to add facial features, patterns and texture. Make sure all clay pieces are firmly attached.
Bake The Clay - Have an adult bake the polymer clay according to the manufacturer's directions. For the Premo clay used in this project, bake the pieces at 275°F for approximately 15 minutes.
Cool Completely - Remove the sculptures from the oven and allow them to cool completely before handling or adding the magnets.
Add A Clear Coat (Optional) - Brush on a compatible clear gloss or iridescent medium if you want to add shine to the finished clay.
Add A Magnet - Have an adult glue one or two magnets to the back of each sculpture, depending on its size. Let the glue dry completely before using.
