It was a reasonably quick knit that I made more difficult by using short rows to shape the shoulders. I didn't want to seam the shoulders, but rather use the Kitchener stitch to join them. Kitchener didn't work out - my stitch quality wasn't good enough. So instead, I did a 3-needle bind off to join the shoulder. Since the length of the arm fell at an odd place, I decided to add a ribbed cuff to complete the sweater.
The sweater was made with Cascade 128, using US 10.5 and US 9 needles.
