My dad and I had an excellent time at our recent visit to color me mine. They have a studio fee of $10 per person but give you a discount on shared paint costs. There are over 50 different colors of ceramic glazes, and turnaround time for completed pieces is one week (sometimes more during high-traffic times, like holidays). This studio is well-kept, and gives you the freedom to unleash your inner artist.
I was particularly touched by the manager's call to me after I had been accidentally overcharged - she offered to correct the issue immediately and her attention to detail meant so much to me as a customer.
