"Potholder"  I found this link and it is a nice example of instructions for a little project.  I would also say it would make great "wall art," which I am considering a creation of an original design in the near future.  Also, note that you can crochet with materials OTHER THAN YARN (plastic strips, rope, hemp, slim line cord, material, etc,..).
