This video explains how to make a polymer clay "rainbow cane," which, amongst other things, can be used to make jewelry or pendants. First, you must run a conditioned piece of each color of clay through a pasta machine. Then, cut each color into a square, and from there cut each square diagonally, creating triangles. Arrange the triangles side by side and attach them together, so that you create a large rectangle of the colors. Run this rectangle through the pasta machine several times, until you create a rainbow colored piece of clay. From there, place the rainbow clay on top of a black piece of clay, roll it up, and you have your "rainbow cane."
