Mix ingredients together until it's the consistency of a cookie dough. (If it seems too dry, add a bit more applesauce; if too wet, add more cinnamon)
Mix in your school glue. I like to sprinkle cinnamon on my counters like I would flour, and then roll out with a rolling pin.
You'll want your dough to be thick - but not too thick that it is unable to be worked with.
Cut out your shapes with your favorite cookie cutter. (We like to use Gingerbread men!). You can also make a small hole at the top - that way you can run a ribbon or ornament hanger through to hang on your tree.
Place on a cooking rack and dry about 48 hours. You can then either paint them or leave them plain. If you have a food dehydrator, you can use that as well (simply cook for about 8 hours).
