This pair of socks is slightly larger than I usually make. It will fit a woman's foot size 9-10. It is made from Opal yarn, 75% Superwash wool, 75% nylon, so can be machine washed. It was done on size 1 bamboo needles. The yarn is a sturdy fingering size, very soft and supple. They will be for sale on the Society Socks website in about a week. A nice find for someone who has a hard time finding larger handknit socks.
