Try it with a piece of paper first. Fold the paper in half and align the bottom of the template with the folded edge. Then draw the line of your circle with a pencil. Cut the circle half and open it up to make sure that your circle is really round (I know that sounds silly, but if the alignment is off, you get an egg). Then repeat with fabric and a small rotary cutter. I find that I must pay close attention to the way I hold the cutter. It is easy to get off onto the next line. U R not alone in this.
