Too-tight sleeve on the right, one-size-up sleeve (unblocked--although I guess that's pretty obvious) on the left. The stitches on the new sleeve look kind of wonky because after I ripped one of the other rejected sleeves, I was too lazy to wind the yarn into a skein, wet it, weight it and rewind it, but hopefully the stitches will even out after blocking.
