Forming clay
Limited only by your imagination. You can use a wheel to throw a traditional pot. You can shape the clay by hand by pinching, smudging, rolling, and or pressing onto or into a form. I have used all methods to form one single sculpture. Throwing pots on a wheel as well as all other methods of handling clay takes practice. The more comfortable and knowledgeable you become with the clay you are using and the chosen method(s) of shaping clay, the happier you will be with the results. Just play with it and enjoy what you are doing. The results will continue to facinate and entertain you as long as you choose to take an interest in the many creative avenues of clay.
