These are COOKIES, and I can think of several different crafty ideas that would work with them. IE: Christmas stamp, wrapped in plastic wrap and hung on your tree. Bake longer on low heat, lots of mod podge (or your preference), and hung as décor such as shown here, ect.
My second community cookie collection - with a Mother's Day theme - is now open on my site. Come see what other cookie decorators are crafting and share your work as well. No competition or prizes (visit my Community Cookie Contest Boards for that); just easy-going inspiration, learning, and fun, about once a month.
