Step 2: Place a piece of polymer clay on the center of the tile between the two 3/8” mandrel. Step 3: Roll out the clay until the roller touches the two mandrels. This will be the correct thickness. Set the roller and mandrels aside. Step 4: Place the cabochon on the polymer clay. Make an exact 90 degree cut around the cabochon through the polymer clay. Remove the excess clay.
