1. For the tub: Tear off a piece of foil about 6 inches wide. Fold it lengthwise into thirds. Turn your cup over so the base faces up. Wrap the foil strip around the base of your cup. As you are wrapping, leave about 1/2-inch overhang that can be folded over the base of the cup (figure A). This becomes the mold for your tub.2. Condition 1-1/2 ounces of the silver clay. Make a log of clay about 1-1/2-inch wide and flatten with your fingers. Roll the log sideways through the pasta machine on a #2 setting. Lay the strip of clay on your work surface. Use the straight blade to cut both long sides so your strip is 1-1/2-inch wide and has smooth edges.
3. With the acrylic rod, press/roll one of the edges flat. This will become the edge of the tub. After the whole length has been flattened, roll the clay edge back until it touches the thicker edge (figure B).
4. Pick up the strip of clay and wrap it around the foil-covered cup. Be sure the straight cut edge is even with the bottom of the cup. Cut away any excess silver clay, smooth the seam, and press the clay against the mold.
5. Roll any excess clay back through the pasta machine on a #2 or #3 setting. Cut a circle out of the clay that is the same size or larger than the bottom of the cup. Press this circle to the bottom of the cup, making sure it touches the clay edge all the way around. Cut away any excess clay and smooth the seams.
6. Using your turkey lacer or small knitting needle, detail the sides of the tub. Draw two or three parallel lines all the way around the tub.
7. Optional detail: If desired, add a large jump ring (or 5/8-inch circle of silver wire) to each side of the tub. These need to be placed just under the rim on opposite sides of the tub. To attach the rings, roll two pea-sized balls of silver clay, flatten the balls, and place one over the top edge of each ring. Press into place. Detail can be added to the handles by gently poking the top and bottom with a turkey lacer or knitting needle (be careful not to poke through).
8. Slide the tub off the cup. Bake at 275 F degrees for 20 minutes. Let cool before starting Santa directions.
9. To make Santa: Condition and marbleize equal parts pearl and cobalt blue clay (about 1/2 ounce each). Roll blend through pasta machine on #2 or #3 setting. Cut a circle of the blend using a cutter that is the same size or a bit bigger than the inside of the tub.
10. Tear off a strip of foil and crumple it. Don't worry about crushing it to get all the air out; any bubbles that result will just add to the look of your ornament. Place a crumpled ball of foil in the bottom of the baked tub and flatten until the tub is about half full. Cover the foil with the clay circle.
