My friend David has been selling t-shirts through this company called Skreened. Basically I upload images to my shop and they do the rest. I make almost no money, but I also don’t have to do anything besides make the image. Right now I have 7 designs up, but I plan on adding more soon: Forming characters and other drawings.
The cool thing about this site is you can choose what kind of shirt you want it printed on. Pretty neat.
