These were such fun to make. Millard did a great job with his pattern and instructions. I used Knit Picks Stroll Tweed Down Heather yarn, fingering weight, 65% Superwash Merino Wool, 25% Nylon, 10% Donnegal Tweed. I'm not someone who wants to fuss over socks after they have been made, so I chose this yarn because I can wash and tumble dry them. They are so soft right off the needles that they can be worn immediately. I will give mine a go round in the laundry tonight and they should get even more cozy. They are nice and warm because of all the cabling to capture and hold the heat. I reinforced the toe using a double strand of the yarn from the center pull.
Update: I just washed and dried these in the machine and they came out wonderfully well. They are so soft and warm; a great tribute to the yarn.
