Wow what a find! Was paying a fortune at those studios, found them online
www.ceramicartspace.com. They were more than 70% less for all the bisque dishes and tiles I bought compared to other places. I ordered online and chose will-call and picked up my order within 2 hours! They are not a store but who cares, I'm saving a lot and they have everything I need for painting my ceramics!!! Very friendly, helpful and knowledgeable !
