With all of my mouth-drawn art, I begin with pencil and paper. Then my girlfriend and I discuss colors to be used–colored pencils. At that point, she sometimes helps me do the first layer of color, and in the end, I add shading with colored pencils.
As of right now, until I can afford better computer equipment and hardware, I outsource the job to turn my creation into a portable network graphic –PNG. I size the images on shirts and have been printed off…Ta-Dah!
