We started with a slab of clay. Then we smoothed it out and cut in into a circle shape. After we added different shape coils on top of it. You roll a thin layer of clay back and forth until it is rounded. Then you smooth them on one side and scratch and attach them together. A good coil is one that is even, thin and smooth ( on the side that is on the inside). I made three different coil shapes. The first shape I used was a circle coil. Then the next one I used was a square coil. The last shape I used was a zig-zag coil.
