Sleeve frustration

Well, I've mostly finished the cardigan I've been working on. I say "mostly" because I just completed the second sleeve...and I think it may be too short. (This garment was begun in my "Gauge swatch? We don't need no stinkin' gauge swatch!" days.) As someone whose arms are often just a tad too long for whatever size garment I'm wearing (what I really need is a size S shirt/sweater/top with size M arms), I have a fear of knitting sweaters with too-short arms. This fear resulting in Sylvia's first sweater, which has arms long enough to suit an orangutan. Anyway, now it looks like the sleeves for the cardigan are too short. I can either undo the bindoff and add a bunch of rows (which probably won't work, 'cause the bottom of the sleeve will still be too tight for a chubby baby wrist) or completely redo both sleeves. It looks like the latter will be the best option, but right now I'm feeling too annoyed to do this. Project Completion Satisfaction was within my grasp...only to be snatched away at the last minute by too-long sleeves. Grrrrr.
