I forgot about the circle!!!! :oops: At the stores they have rolls of paper that kids use. I would cut to the desired say height (5'). Then if you remember as a kid, we would fold in 1/2, then in 1/2 again, and so on till to reached a size that would be workable. Then put your curve on with pencil and then say go down about 10" and place the other curve. Cut along lines and you should have your donut.
