Our Nerd Home has a great guide to the finicky, difficult, but ultimately incredible art of constructing gingerbread polyhedral dice, with a little help from our old friends, graham crackers.
The Gingerbread D20 is a patience-trying project. Consider yourself warned. It is hard to the get the angles right, hard to get the shape to stay formed correctly, hard to get the icing to go on/stay straight, and hard to not eat while you're making it. But after all of the frustration (and snacking), we kinda love it so wanted to share anyway….
…We bought a red "Icing Writer" from Michael's to fill in the numbers. Once the Gingerbread D20 was done, we used extra graham crackers and white chocolate to make a D6 and D4, which were MUCH easier.
