So here's a great recipe for making snowmen and other figures for the yard on your gingerbread house:
1 tablespoon shortening
1 tablespoon Karo syrup
1 cup powdered sugar
Add the powdered sugar to the shortening and syrup a little at a time. Knead until pliable like clay. You can add 1/2 teaspoon mint flavoring and 1/8 teaspoon salt if you think you'll eat it. the clay can be colored with food coloring for making little people, animals, etc. Cute stuff!
