Preheat oven to 275 °F. Test temperature with oven thermometer for perfectly cured clay. Condition all clay by kneading until it’s soft and smooth or running it through the Clay Conditioning Machine for several passes on the widest setting. Fold the clay in half after each pass and insert the fold side into the rollers first.

Remove the ink cartridge from the BIC pen with the needle nose pliers and set it aside.

Roll out 1 sheet of each color, about 1/16" to 1/8" thickness. Place one sheet on top of the other. Starting at one end roll the clay together jelly roll style. You will now have a long coil of clay.

Gently roll the coil on your work surface so the coil is about 3/8" wide. You may want to set the cane aside to let it “rest” doing this will allow the clay to firm up so it is easier to slice.

Slice the coil (referred to as a cane) into thin slices with a sharp knife. Save extra slices for covering the pen holder (directions below).

Cover the pen all over with the slices you have made.

Gently roll the pen back and forth on your work surface. Don't roll too much, just until the clay is flat. Over-rolling may cause the clay to pull away from the pen.

Trim the ends of the pen case and use one slice to cover the end of the pen. Blend it in.

Bake at 250 °F for 15 minutes. Sculpey III usually cures at 275 °F, but in this project you want to cure at a lower temperature to keep the pen from distorting. .Always check the accuracy of the oven by using an oven thermometer. Use a timer to avoid over baking. Over baking may cause your clay covered pen to darken. Use an oven-proof baking dish lined with index cards. Do not exceed the temperature or baking time so you do not melt the pen. Do not handle the pen until it is completely cooled. Replace the ink cartridge when cool. To push it in completely, press the ink tip into a layer of something soft and stand the pen up. Press the clay cover pen case down onto the ink cartridge.

Shape a piece of aluminum foil to resemble the shape of the pen holder in the photo.

Cover the aluminum foil with a very thin layer of clay so that it is the shape you want. Cover the pen holder with slices of the jelly roll.

Push your cooled pen into the base, so it will fit in after the base is baked.

Bake the base at 275 °F for 10 minutes. Always check the accuracy of the oven by using an oven thermometer. Use a timer to avoid over baking. Over baking may cause your pen holder to darken. Use an oven-proof baking dish lined with index cards.
