Here is my finished sweater:
I used Brown Sheep Cotton Fleece, which I liked. I had to make a lot of changes (I had it mostly done and took it back out to the armpits once to make the sleeves and the yoke shorter), but I think it would have been fine if I had just knitted a smaller size in the first place. I also added a ton of extra rows so it wouldn't fall off of my shoulders. If you're interested there are some "in progress" pictures on my blog, which I never got around to posting here. I really liked knitting this sweater and I'm pretty happy with the way it turned out and I may do another one sometime.
