Cover the cardboard with foil. Spread the foil with white frosting.
Add 2 mini candy canes to the frosting on the board (look at the photos for specific placement). Spread a little frosting on a ¼ graham cracker, and stick that to the top of the candy canes to create the base of the sled.
Add a little frosting to the top of the graham cracker. Stick a gingerbread man into the frosting on top of the sled. Repeat to create more gingerbread sleds on the board. Decorate the board with holiday candies. That's it!
The gingerbread sleds can be eaten, or you can leave them out for display and decoration!
