Tweed Sock is a hand-dyed yarn by Mollie Klein.  A skein is composed of Superwash Merino and Nylon (80/20).  Within the yarn are small slubs that give it that "tweedy" look.  One skein of Tweed Sock contains 400 yards on a 100 gram skein.  Suggested Needles for socks are sizes 0 - 3.  Machine wash, cold and gentle, lay flat or hang up to dry.
