The opposite side of Broken Rib Stitch creates a beautiful textured pattern. It can be knitted as usual Broken Rib Stitch and then RS and WS have to be reversed. Or, to make it appear on the RS at once, row of 1x1 ribbing (alternating knit and purl stitches) can be followed by a row of purl stitches.
This pattern is used to add volume and texture to the garments. It doesn't curl and is a bit flexible, which makes it great for sweaters, afghans, blankets, and scarves.
