From the Stitch Description: Here is a stunning mesh pattern that is useful wherever an openwork is wanted, either in panels or in an allover fabric. It has, as well as clear-cut lace geometry, a three-dimensional quality; the vertical ribs stand out strongly against the crisscross background. In this pattern the central decrease (sl 2 knitwise - k1 - p2sso) is definitely preferable to the usual sl 1 - k2 tog - psso, as the latter will not produce a clean vertical rib and thus the sharpness of the pattern is lost.
