The Overlock Foot #2 is perfect for overlocking seams and hems. It's very good for tidying up basic seams.
The stitches are made over the pin on the inside edge of the foot, which gives them more thread. This keeps the cloth from bunching up and creates an elastic, flat seam. On knit fabrics, the Overlock foot can also be used to stitch high-quality hems, waistbands, and overlock seams.
