3D Cake: (some assembly required)™ Paper Craft Kits, Rubber Stamp Set
What Can You Do With a Piece of Paper? Sliceforms
Cake The Carousel Cake Stamp and Stencil Set makes single layered cakes in three sizes. They can be attached to one another to make a tiered cake, and the largest size converts into a charming carousel. Because the pieces for the cakes are so big, they are only available as Stencils. The complete set includes 3 Stencils for the Cakes, and 20 decorative foam-mounted stamps which include: eight two-sided Carousel Animals (four horses and four beasts), candles, swags, and medallions.

For those who aren't interested in making the Carousel there is the Unmounted Cake which includes the 3 Stencils and 4 unmounted cake decorating stamps.

Unmounted rubber for the 16 animal stamps is available separately as well.
