Versatile, durable, and easy to use, polymer clay has become a favorite for making beads, jewelry, and more. You can even bake this synthetic modeling clay in your home oven. If the color you envision for your project is not available in pre-made clay, you can also mix colors to develop unique hues for your creations. Here's one method for mixing polymer clay colors: Take the proportions you want of each color in your hand, then roll together to form a roll. Bend that roll in half, then flatten it, then roll it again, repeating the process. Try not to get a lot of air in the clay as you fold it together. If air pockets get trapped in your clay, you'll notice that plaques or discolorations may appear on the surface of the clay after you cure it.
