I will tell you that I have used the Elisa's backporch templates and the are wonderful - I wouldn't use any others. I saw her at a QS vending and she told me that her circles were a couple of degrees short of a true circle - although you certainly can't tell that looking at them -they go together easier and due to that difference you don't have to clip you just iron the seam towards either side no problems She also has a couple of books with different patterns using te emplates.
