Oh the joys of trial and error. This is my first original lace cowl attempt, and all things considered, it turned out okay. Not really as lacy as I hoped, but whatever. It actually turned out as a lace rib, which is perfectly serviceable if not as feminine as I was going for.
It's an 8 stitch pattern repeat: *k4, yo, k2tbl, k2tog, yo* on the odd rows, and knit all on the even rows. (Knit in the round, of course).
I used a 9 and would probably have liked it better with a 7, and I think it's a little too wide and too short, but I'm my own worst critic, and I'm sure my friend will love it.
