Wad together scrap pieces of polymer clay into a ball. Flatten the clay using your fingers then run it through a pasta machine.
Identify an area of the clay that has a visually pleasing color pattern, fold the other areas of the clay underneath, then run it back through the pasta machine.
Note: Air bubbles may form when folding the clay. Run the clay through a pasta machine (fold first) to prevent any bubbles from forming. If the piece being worked on requires no air bubbles, pierce the clay with a needle to vent.
Continue to fold and run the clay through the pasta machine until the desired color blend is achieved.
