FOOT #2, OVERLOCK
Overlock foot #2 is ideal for producing serged seams and hems. It is especially well suited for neatening simple seams.
The stitches are formed over the pin on the inside edge of the foot, giving them an additional amount of thread. This prevents the fabric from bunching up and produces a flat, elastic seam. The Overlock foot can also be used to sew high quality hems, waistbands and overlock seams on knit fabrics.
