When I got to the end of the sleeve increases called for by the pattern, the sleeve didn’t seem nearly wide enough to cover the armhole, so I continued increasing every 4 rounds until the bind-off. The sleeve fit on fine.

This took way longer than expected after I grabbed the wrong skein of yarn for one of the sleeves -- it was very close in color, but not exact, and I didn’t notice until I was nearly done with the sleeve. Oops.
