Great tutorial, Rhonda.
If anyone plans to make lots of these flat circles, there is a great product available called "Perfect Circles" (by Karen Buckley)
They are mylar circles that can be used instead of the cardboard template. There is a small set (7/16" to 2" ) and a larger set (2 1/2" to 4 1/2" ) I have the small set and love it.
Easy to trace around, won't warp when pressed (within reason), and give a nice crisp edge to the circle. Worth the expense if you make circles A LOT.
