J.,
I've done in the past with my kids a painting ceramic party. I googled and found 2, one in Southlake and one in Coppell. The one in Coppell has a website, but its under construction, so here is the info:
ART FROM THE HEART
Paint Your Own Pottery Studio
COPPELL TX

Here is the info for the other place:

What they do is for a fee they pick a ceramic piece and you can pre-choose certain pieces in a price range, so they don't pick platters or huge piggy banks or something. They usually charge you for the ceramic piece per kid and for a group charge they provide the paints and materials and they glaze it in their oven and you should be able to pick the pieces up in a week or so. It would be cool to take polaroids of their finished pieces for them to take home until they get their piece back or digital is fine and then you could put the pics in their thank you cards. Some places allow you to take a cake or treats. Hope this helps! And I hope your daughter has a great birthday. Let me know if how it goes if you decide to go there? Take care!
