Well, I got the backbox sides scanned in and then I painstakingly stitched them together and had traced everything in Illustrator to get a nice vector image with a layer for each color. This will make it nice and simple to be turned into stencils. I borrowed a Magic Wand scanner from work to test out. It worked surprisingly well for the backbox but when it came time to scan in the cabinet side, it didn't work out so well. Here's how the backbox looked after I stitched it, and then after the vectorization was complete. Now time to work on the cabinet art.
