Haley's Comic has a store! It has t-shirts, greeting cards, mugs, and more things added randomly. Some of the designs are from my blog, and some of them are just random things I came up with and thought, "You know who should know about this? THE WORLD!"

A note about t-shirt printing options: Zazzle lets me either make all the white areas of a drawing transparent, or none of them transparent. So if I take pretty much any drawing where someone has teeth or eyeballs, and I try to put it on a black background, I either have to put a big, unwieldy white square around it, or give everyone black teeth and black eyes, like monsters. Therefore, most designs are only available on white t-shirts or lighter colors, although I do try to branch out and make darker t-shirts when I can.
