Step 2: Head Shape
Yoda: "With triangle ears create the head round. To create the ear crevice use a toothpick. Yes, hmmm. To while you work put the head on a toothpick. Hmmmmmm."
You will need green clay and create a basic ball shape, from that shape pinch out the ears and smooth the head shape. The ears are in a triangle shape from a round head.
Use a toothpick to create the ear crevice, you might also want to put the head on a tooth pick to avoid some fingerprints while you work.
