Private birthday parties for adults at Pottery Studio 1. Invite 3 to 20 guests and take a memento home regardless of prior experience. *** Each guest will take home a memorable keepsake: a cup, pot, or bowl of their own design. Guests will throw their pieces on a potter’s wheel and paint them themselves. *** You can bring food, drinks and a birthday cake and set them up in the workshop. We have no extra charges.
