I borrowed my mom's hot glue gun this afternoon and attached the ornament hangers to the backs, then painted the embellishments. I think they turned out pretty cute, and I love how it makes our go tree smell like cinnamon.
Here's the recipe I used:
In a medium bowl mix together 1 cup ground cinnamon and 1/4 cup applesauce using a rubber spatula. Stir in 1/2 cup craft glue. Stir the dough until the consistency is smooth and dry. Let sit one hour. Roll out to 1/4 inch thick. Cut with cookie cutters. Let dry overnight or two hours in an oven heated to 200.
