Use the seam circles to adjust the size of your patterns or add a seam allowance. Place the tip of your pencil in the centre hole, and keep the edge of the circle on the pattern line as you trace. You can use a tool or your hand to keep the edge of the circle on the line, or simply keep your eye on the edge of the circle. Adjust your pattern from 1/4" to 1" depending on the circle you use.
