Each brand of machine is slightly different, but the basic stitches that can be made are the same. Here, you’ll see examples of sewing done on a Husqvarna Huskylock 936. Using three rows of the thread rather than two allows you to hold the fabric “down” more than two rows of stitching would, therefore adding stability to the hem. This would be a necessary stitch for a fabric that would naturally roll or not lay flat.
