Since I had experience in making one sweater under my belt, I felt fully empowered to make modifications. (Ahem.) I had made this sweater from this pattern before and so I knew what changes I wanted to make. Primarily, I wanted to add buttons. Secondly, I wanted to make the project quicker so I decided to knit it in the round. I think I managed to shave an hour off the total knitting time.
My full knitting notes are here.
