Q: Is it messy?

Every time I travel, I bring a piece of canvas with me to put beneath the wheel.  So, no, it's not messy nor does it need any special requirements for you to provide to keep the area clean.  I often say, "I've spoken in churches with pink carpet and all is well when I finish!"

Q: What ages is the potter's wheel for?

Everywhere from ages 5 to 90!  Audiences of all ages have been enthralled by watching the wheel.

Q.  Do you sell your pottery?

Often I will bring oil lamps to sell when I speak.  Currently, I don't have any for sale in other venues.
