So, I picked up what was left to be done and finished the sock. Yes! Finished!
When I started this sock, my major concern was to find a way to make a really stretchy cuff. I was never totally happy with the elastic experiment. First, the colours didn't match. Second, there is always the possibility that the elastic gets lax.
And this was when I felt maybe the holding up of the sock was a blessing. I love how the neckband of Husband's sweater was done because it gives a nice stretchy finish. Then, why not use it on the sock cuff? Only that I had to whip stitch the live stitches really really close ... maybe just 2 rows down:
