I found a large red oval. I had made this by choosing the oval option in Corel Draw and making a whole page of ovals and circles to cut on the vinyl cutter. Since the Tech Shop http://www.techshop.ws has nice selection of vinyl at a reasonable price - I have a nice collection of colors. I have used them mostly to make name stickers for the grand kids.
I had also cut out animals using the animals file in Corel Draw clip art and choosing those with little detail (shadow drawings are the best) and nothing too delicate. (I kept losing the antlers on the deer)
