Hand-painted pottery has a rich legacy of storytelling, from the Grecian urns that document the perils of Orpheus and Eurydice to modern coffee mugs that foretell epic tales of the world's greatest grandpa. Paint your own story with today's Groupon: for $10, you get $20 worth of paint-your-own pottery at Toys on the Square in Hummelstown. This deal is valid for ages 4 and up. Toys on the Square charges a studio fee of $8 per person, piece, and session that includes supplies, glazing, and firing.

Toys on the Square’s 8,000-square-foot space and 50 paint-your-own pottery stations accommodate unusually popular birthday boys and girls as they unleash their rabid creativity alongside all their friends. Artistes can start by choosing a piece of pottery from the hundreds of available mugs, vases, plates, and busts of the cast of Who’s the Boss ($7–$20 for the average piece), then lay claim to their favorite color glazes. Toys on the Square injects fresh inspiration into the air with design books, stencils, and stamps, and the tile wall lets painters preview what each finished color looks like. Once Da Vinci devotees have signed their name to their objet d'art with a permanent glaze pencil, the staff will coat it with a layer of clear over-glaze and then fire it in a kiln. All glazes are nontoxic and lead free, ensuring that finished pieces are safe for eating and drinking. Pieces will be ready for pickup or shipping in three weeks.
