I thought since I'm trying to learn Illustrator, before painting the cans, I'd use the sketches to do some color vector illustrations. Besides this I've done a couple tutorials through vector tuts, but thats about it. Here's an in-progress shot for the Ultraviolet Cafe trash can. I used the pen tool to trace all the lines in the sketch. Then, I filled in colors and removed the outlines to start to get a sense of what it will look like eventually.
