I did the secret-ninja snip, knit, and graft to lengthen my Hopeful. I'm very pleased with the fit now. I think I used the wrong size needles, though: I started with size 6s but the fabric looked too loose, so I frogged back and switched to fives. I think 6s were the correct choice after all. Oh, well. It shouldn't be too noticeable once I even out the tension on the transitional rows (particularly the grafted row) and then block it. (The rest of the sweater was blocked in September, so it has had a chance to relax, while the inserted section hasn't.)
My next step is to make the sleeves longer. I'm not sure if I'll take them to 3/4 or full-length. It may depend on how much yarn I can get my hands on. Knitpicks is discontinuing this yarn and they're out of grey. I contacted a user on Ravelry who has two balls in her stash, but I haven't heard back yet. I'll be crossing dye lots, but I think it won't be obvious if I use the same dye lot for the entirety of both sleeves, rather than switching part-way through the body, for example. We'll see!
