I've been playing with a polymer clay technique called Crushed Velvet. It is a mica shift technique where you run the metallic clay through the pasta machine a bunch of times to line up all the mica particles, then you put the sheet of clay through the fettuccini cutter which slices it into little tiny strips. Then you mush up the strips into a cane. You take a slice of the cane and turn it into a veneer and then make what you want. You get a 3D effect even though you used only one color of clay. I made some earrings and a couple of cabochons. Fun and pretty.
