Measure to the right of the needle and tape a thumb tack with point up. Put the tack about 1/2" larger than 1/2 the diameter of the disk. Place the fabric with center punched down over the tack. Then slowly stitch with basting stitch turning the fabric as you stitch. This will give you an even circle of stitching. When finished then gather up the fabric around the disk. Tie thread and even out the edge. Spray edge with starch and remove the disk. You should have a good circle to then applique to base fabric.
