The Dirty Dozen are a group of 12 that make projects for a special gallery called the fan club gallery. This gallery is only available to those that have a paid membership, but I'll tell you, it's worth every penny and at a very reasonable price. The money helps to support this wonderful website that most of us spend way too much time on, lol
