The pattern is "Cat-oween", and it's mostly stranded knitting with two colours in a row. There's some purl action, and in the crown part, you have to juggle three colours in a few rounds.
That was... awkward, but I did manage.
The pattern was nice to work, the yarn was pleasant (it's smooth and not very elastic, but feels really nice against the skin), and I had a blast knitting this. Bonus: The recipient really liked it, too, and it did fit. Yay!
I even managed to finish it before Halloween... and now I'm tempted to make another one of these with the leftover yarn (which might be juuuust enough for one more). Eventually.
