While it may seem challenging enough to learn to sew a straight seam, eventually it is necessary to learn to sew in curved lines or a circle. Quilters, in particular, need this know-how, but also those making stuffed animals or dolls. While experienced seamstresses may sew a circle freehand with only a seam marking to guide them, others may need some help to achieve the perfect circle. Practice circle sewing on scraps before attempting your project if you have not done circles before.
Mark the circumference of your circle on your project lightly with fabric marker or pencil.
Cut a circle template from the cardboard or plastic slightly smaller than the circle you plan to sew. Cardboard from a writing tablet or plastic from a margarine tub lid would work well for this.
Lower your needle into the fabric along the edge of the circle you wish to sew. Lower the presser foot and place the template along the outside edge of the foot. Begin sewing, using the template as a guide.
Sew slowly. Stop and reposition the fabric if it begins to bunch.
