An Overlock, Cover Hem, and Top Cover Hem. It is versatile, incorporating many flatlock, blanket and overlock stitches, as well as the chain and coverstitch. You won't need to change the needle plate or foot for a rolled hem, and the upper looper system is easily converted for a cover hem or top cover hem. The 1200D automatically selects the tension settings for each stitch so you can sew with comfort and confidence. You'll also find 28 optional feet and attachments.
