more sweater progress

I finished the first sleeve of E's sweater last night at my knitting group. Unfortunately I forgot to bring the last ball of yarn, so I didn't make any more progress. I had E try on the sweater to make sure I got the sleeve length right. The sleeve looks ok, although next time I would do the arm decreases a bit differently (more rows between decrease rows to spread them out). I tried a stretchy bind-off for the sleeve, found here. It looks alright; it's definitely stretchier than what I would normally do, but I suspect something like a sewn bind-off would be better. I couldn't find the book that supposedly has the instructions for that, though, so I went with a simple BO.
