This was really easy to do. I had some pre-cut cake circles (in the cake aisle at Hobby Lobby) and taped three together. I used 6-, 8-, 10- and 12-inch circles. If you don't have any lying around, you could use any cardboard or foam board. I just happen to be a girl who has this kind of thing waiting around for a raining day.
Use a hot glue gun to affix some ribbon to the edges. Then take the tomato sauce cans and cover them with scrapbook paper. Glue the cans in between each set of circles and you're all done. It only took about 10 minutes and I think it made the presentation look a lot better.
Oh, and the muffins were delicious.
