Trying to figure out the cost and how this works. Do you just pay for what piece you decide to paint or what?

Yes ,I had a piece Done for my granddaughters birthday.they painted it for me..or you can paint it yourself..each piece is a different price. I paid in advance. I hope this helps.

You pick the piece you want to paint, paint it and once you are done pay for it. Price varies by design and size of the pottery. You then go back in about a week to pick it up after its been fired.
