It's Berroco Ultra Alpaca, and the pattern is something that I made up when I didn't copy down the stitch pattern from a book correctly. Dang it. Oh well. By the time I realized that I was making an accidentally-striped sock, I'd gone too far.
This yarn is not my favorite. It's splitty and fuzzy. The fuzzy is less of a problem, because then the 8 pounds of cat fur that inevitably get knitted in don't show so much. At least it was cheap.
Today in my meeting, I forgot how to turn a heel. I had to rip back like 3 times. It's hard to seem like you're paying attention when you're counting, ripping, untangling what you just ripped, and whispering to yourself. Oops. Sorry, other meeting people.
