The cover stitch is especially suited to stretchy fabrics like knits, as well as the popular new blends of traditional woven fabrics with a small percentage of stretch fiber added for extra flexibility. The Coverstitch series machines are ideal for constructing projects from fashion tops to competition ice skating costumes.

The cover stitch is a serger-type stitch made without the knives (no fabric is cut), so it can be used not only to finish hems, necklines, collars and cuffs, but also for decorative effects in the middle of the fabric. Cover stitches can be made with two or three needles. For example, a double needle cover stitch will show two lines of straight stitching on the top of the fabric with the two lines joined by a looping stitch on the bottom side. Because both sides of a cover stitch are finished, it looks great with decorative thread.
