I cut out my circle and then folder the circle in half and then half again to find the center and placed a dot with my ink pen. Then I drew another circle on the back of the leather in about 1/2 inch. This was going to be my sewing line. I knew I had to be perfect the first time because you cannot rip out mistakes without the holes showing.
