Add the applesauce and cinnamon to a mixing bowl, and mix together until you can form it into a ball. Ours was a bit dry and not sticking together well, so we added a bit more applesauce to get it the right consistency. You don't want it gooey, just add enough applesauce so that it holds together.
Divide the dough into thirds. Get out some plastic wrap and put 1/3 of the dough between two pieces of plastic wrap. This is optional, but it's a lot easier to roll out with the plastic wrap. Otherwise, it tends to stick to the rolling pin.
Roll out the dough to about 1/3" or 1/4" thick. I wanted smaller ornaments, so we used smaller cookie cutters and made them about 1/4" thick. The thinner ornaments dry faster, but they are a bit more fragile, so keep that in mind when you're deciding how thin to roll them out.
While still on the plastic wrap, use the drinking straw to make a hole near the top of the ornament. This will allow you to add ribbon or twine for hanging (after they are baked).
Transfer cutout shapes to a parchment-lined cookie sheet.
Bake at 200° F for 2 to 2 1/2 hours. The amount of time required for them to dry depends on how thick they are. They smell so good when they're baking!
After they've thoroughly dried in the oven, add ribbon or twine. Enjoy your handmade cinnamon ornaments!
