Used Cat Bordhi's DIY pattern, modified by making a “good” mistake. I cast on then increased using yarn overs, then knit the pattern.
The end result is a slightly more lacey “ring” rather than cowl. I love it.
What did I do?
I cast on per the pattern. Then I mis-read, and started on the "lace edging", doing this:
Round 1: *[Yo, k1] 2 times, [yo, k2tog] 3 times. Repeat from * to end of round.
Round 2: Knit.
Begin diagonal lace pattern:
*Yo, k6, k2tog. Repeat from * to end of round.
Knit one round.
Repeat last two rounds 10 more times.
Then, because I had but one skein of expensive 100% angora, I ran out of yarn. Not to worry. I knit the garter edge in black angora yarn. And, really, really, even if I had had enough yarn, I would probably have elected to do a black border.
I am not a huge fan of mobieus garments, but in this case, it's a winner. The way you knit a Cat Bordi mobieus is to actually knit it, rather than knit a rectangle and do a half twist, then join it. As a result, you knit one round, and you've knit in two directions - half knit side, half purl side. (You have to see it to believe it, and even then, you may not believe it.) For this scarf, this enables you to fold the circle in half and still have knit side facing. This was such a fast knit, I want to make more, more, more.
