- First I made slab then I trimmed a base with the top of a cup. After the base was completed, I built up using coils, dots, and braids. For the coils, I made swirls ranging from large to small, but while I rolled them up, they unfortunately cracked and split. The other two designs I included were dots which I just rolled circles, and then the other were braids were I made long coils that I braided together. Once the designs were in place I smoothed the inside to connect everything. - A good coils is smooth, doesn't have any cracks, and even throughout.
