I finished sewing this sweater about a year ago. Since, it's just been sitting in my knitting pile, waiting for a zipper. For some reason, this seemed totally daunting, and I've been putting it off ever since. But as it turns out, all you do is sew it in! Like, as if it were any other fabric. I think it took me a total of 10 minutes, including googling how to do it.
So now I have this insanely warm sweater, made from opossum wool I bought when I was in New Zealand a few years ago.
*sorry for the blurriness. The auto focus on my camera is going loopy, and there are so few daylight hours these days.
