Lava Flow Cowl, free pattern from the DixieStix
blog. I had two skeins of Debbie Bliss Cashmerino Chunky and a pair of US 10.5 knitting needles that I was okay with losing if airport security decided to confiscate them, so I took this on a very long airplane ride and it was great! Until I ran out of yarn.
It's not long enough to make a comfortable cowl, and this yarn has been discontinued, so I'm going to frog it and make something else. I'm okay with that; I cast on another one in a different yarn and this time I made sure I have enough!
