From the Stitch Description: The outlines of this design happen to be filled in with twisted ribs - this is traditional - but they could be filled in with garter stitch, seed stitch, moss stitch, or plain stockinette. With any “filling” you like, this is a beautiful pattern for fancy sweaters, afghans, or dresses.
