I just finished this sweater last night. I made it using mission falls wool. I was trying to find buttons that were the same color but couldn't so went with a dull silver button. Overall I am really happy with how it turned out. I got the pattern from http://www.cosmicpluto.com/blog/?p=646
I did modify it a bit. I did a couple more decreases at the neckline before casting off. Which is why I have more buttons then I am suppose to for my size. I also made it a little longer before attaching the sleaves.
