Add water, 1 cup at a time, and mix with your hands. Stop adding water when the dough resembles the consistency of play-dough. It should hold together and be workable into shapes.
Shape your ornaments into any (flat) shapes that you’d like. Use cookie cutters, a knife, or simply your hands to do this.
Poke a holeĀ at the top with a stick or something similar. It just needs to be big enough to feed a string through later.
Oil your cast iron skillet or pie iron, and place ornaments inside.
Place ornaments in or over the campfire in a location that doesn’t get direct flame. Let dry for up to 2 hours, until ornaments are hard.
Let cool, and paint or decorate with markers. Hang on your tree.
