Sock yarn is different than regular yarn. While most worsted yarns have a number 4 next to them, sock yarn has a number 1. It is much thinner because that thick yarn would make a really uncomfortable sock. Deborah Norville's Serenity sock yarn is one of the best sock yarns I have ever worked with. It is very soft, tangle free, and the socks made are extremely comfortable. Sock yarn needs to be able to breath yet be absorbent to keep feet free of perspiration. This yarn does the trick and socks I make with this yarn are some of my family's favorite.
Deborah Norville Serenity sock yarn is a blend of washable Merano wool, rayon made from bamboo and nylon. It is the perfect combination to result in a great sock. The socks can be washed in the washing machine in cold or warm water, but the sock does best when turned inside out when washing. They can also be dried in a low heat drier and come out looking beautiful. There is about 230 yards in one skein of yarn, and I usually use 2 to 2.5 skeins to make a pair of adult sized socks. The yarn also makes really nice lacy scarves and some soft baby sweaters.
