What a great learning experience this was. Here is the finished sock. Now, on to the next one! I took a chance and estimated how much extra yarn I would have and decided to double up on the strands on the toe so that it is reinforced. I had enough, thankfully. I think I still have enough that I may go back now and add some after-the-fact reinforcing to the heel, so holes don't grow there as I wear these.
Millard, your pattern is brilliant! Thank you.
