If you want to turn your sewing machine into a serger, this attachment will allow you to cut the seam edge and stitch in one step. Use Straight Stitch, Blind Hem, or Stretch Hemming Stitch (sewing left primary to right cut of seam). You must feed the fabric up and over the cutting edge part, and guide the sewing part of the fabric under the foot. Much like using an rolled hem, or binding foot.
