From the Stitch Description: This pattern is similar to the Crochet-Knit Shell Pattern, but with a few significant differences. The loose and wavy quality of the crochet-knit version disappears here, to be replaced by a square filet-like effect. The mesh is firmer, and therefore applicable to a wider variety of uses. The pattern is worked from the wrong side instead of from the right side, and it goes more quickly and easily.
