From the Stitch Description: Arrowhead Lace consists of panels of Lace Trellis placed so that the left bias and the right bias counteract each other. The panels can be made wider simply by adding four more stitches to each repeat for each extra diagonal rib desired (i.e., one extra “yo, ssk” on the right-hand side, and one extra “k2 tog, yo” on the left-hand side; or two extra each, etc.) Arrowhead Lace makes a beautiful , crisp-looking insertion in stockinette fabric, or a mesh-like allover pattern. This is Arrowhead Lace in its smallest possible dimensions.“
