To do this project, I simply found some Halloween silhouette clip art at Clker.com and cut the images out with my Craft Robo. You could just as easily trace the image onto the vinyl, if you didn't have a vinyl cutter. I would just make sure to only choose images that are easy to cut out without any real intricate and fragile edges. Once you have your design cut out, just peel it from the backing and apply to your cabinet.
