whatever you choose to make- keep it wet whilst turning (be carful of electrics) dont go for a tea break as it will be distorted by the time you get back, turn it consistentley thin and wet sand it. it will start to warp almost imediatley- after you part it of-if you hold it to your ear you will hear the cells popping, within 48 hours it will be completley finished moving.
its a joy to turn and makes the workshop smell lovely.
