Only a few, but I have some Tshirts up for $20. 
Got some t-shirts with Uluri, Sin, and Kindling, the Chibi shirt, and a Fox SHirt. I also have shirts with the artwork "Jar of Adorable" and "Forest of Souls" featured on them. 

Eventually... I want to make more shirts for people to enjoy and get. I've always wanted to make art that looked nice on shirts.
