I started the cowl with a long-tail tubular cast on and attempted to finish it with a tubular cast off, but my tubular cast off wasn’t stretchy enough, and it snapped when I tried to stretch it, so I unraveled several rounds of the cowl, redid the ribbed edging, and then used the invisible ribbed bindoff, which turned out much better than my failed attempt at the tubular cast off.

I had originally planned to knit until I ran out of yarn, but the cowl would have been too wide had I done that. I think I have enough yarn left to knit an earwarmer.
