I love, love, LOVE this sweater. It fits beautifully, and I’m absolutely making another one. However, there are some things I would do differently next time:

1) Make sure I have 3 complete skeins of yarn. I wound up having to make a teensy collar, which worked out really well, actually, but I’d like the choice to do a wider one if I wanted. (I used every little bit of the yarn I had.)
2) Make the sleeves longer. I wanted them to be full-length sleeves, but they wound up being more like 3/4-length. It still looks good, but not what I originally had in mind.
3) Do a slightly deeper armhole, say 1 1/2 inches instead of just 1. (As in, knit about 1 1/2 inches after attaching the sleeves.)
4) Do less shaping on the back of the neck. It doesn’t need to come up that high in the back.
