Like feline fanatic, I use a compass to draw my circle on cereal box cardboard and then cut it out with scissors. I cut the fabric using the cardboard template and adding a seam allowance. I then lay the template in the center of the fabric circle and give it a good spray of starch so the seam allowance gets wet. Then I press the seam allowance up and over the edges of the template until they're dry. Perfect circles every time with no starch on the front of the circle.
Here's one result. The smaller circles are appliqué, the large ones are pieced.
