I know what you can do.
After coming up with a design of your choice, you can print it on those special papers that you can iron on to shirts. After printing the design with a laser printer you can then iron it onto the shirt of your liking, cotton works best. The thing abou these shirts however is that they fade or the pictures crack fairly quickly (if you was with hot water at least).
If anyone comes up with a good design can they send it to me?
