How to Throw Taller Pots

Use a Strong Point of Contact: Some potters prefer to throw with their fingertips when they throw smaller pots like mugs or cups. They get a better feel of the wall thickness that way. But when you are throwing large pots it may be a better idea to use your knuckle or even the palm or heel of your hand.

Most potters also keep their inside hand slightly above their outside hand as they pull up the walls. Your top, inside hand pushes the clay outward and then your bottom, outside hand lifts the clay and pushes it back in.
