This lace edging comes from Weldon's Knitted Edgings and Insertions No. 442, Vol. 37. I am using it for a shawl knit with my Silk Camel yarn.
It knits up quickly and is an easy pattern to remember.
I have tweaked it ever so slightly by changing the last stitch on the ws rows to a knit instead of a purl. The pattern instructs to just slip the first stitch on rs rows - I slip purlwise with the yarn in front, so by knitting the last ws stitch instead of purling, I have a nice clean edge to pick up for my shawl. There are of course other ways to get the clean edge, but this way is my preferred method.
Cast on 8 stitches
Row 1: (RS) Sl 1, k1, yo, k2tog, k2, yo twice, k2
Row 2: yo, k2tog, p1, k1, p to last st, k
Row 3: Sl 1, k1, yo, k2tog, k to end
Row 4: sk2po, p to last st, k
Repeat these four rows for the pattern. Happy Knitting!
