I also love raiding the kitchen for tools, as they said you can get some of the best sizes for a great price! Whenever we lose a lid or the bottom for a piece of tupperware the lone piece gets carried away to my scrap room. I also have a scratched CD I use for medium and small circles. I also hunted down a roughly 10.5" plate at the thrift store that now has a permanent home in my scrap room.
