Luckily, I had knit Fauxnel top-down so it was an easy job to undo the cast off, thread the needle thru the stitches (thank goodness for ravelry as I had forgotten the needle size) and keep on knittin'.
Finished, worn and complimented last week, I now have a much more usable garment.
In progress, one sleeve lengthened, one on the needles.
My fingers are placed about where the shorter sleeve ended, showing the amount of extra I added.
Lookin' good, I think.
