I only wish I had more time to spend at Creative Escapes. I recently went there with a group of friends and absolutely loved it. They offer all sorts of paint your own pottery as well as mosaics and other crafts.
They offer studio time for parties and get-togethers as well as regular hours that you can go in and paint. They were also nice enough to let me take my project, and some paint, home to finish. They fire your item and you pick it up the next week.
The prices are reasonable and everyone there is friendly and helpful!
