"Norse socks were not knitted, which apparently was unknown to the Norse. Instead, they were made using an ancient technique called nálbinding (needle-binding). Using a single large, thick needle, it was a method of knotting the yarn. Although time consuming, this approach resulted in a nearly indestructible garment. If the thread were to break or wear out, the garment would still be intact, since the thread was everywhere knotted to neighboring threads." This sock found in York.
