I made a design that I plan on sending to Threadless, last night. Eddie made one too, and be sure to give it a 5$ rating because it's mondo cool. The original is on paper because I went low-tech last night, but I drew a rough copy on paint so you can get an idea.
Obviously, the final product won't look anything like that. But you get the gist.
It will be awhile before I ever send it in, and I'll have to bone up on my graphic designing skills which at the moment are non-existant. I'll also need a better computer.
