These socks are inspired by the traditional knit patterns of Sweden, passed down from old, creations from only needle and yarn. Take that to Trivia night. These socks use Dralon cotton yarn, a cotton and acrylic mix yarn. Cotton by itself tends to result in socks that gradually become rougher and stiffer over many washes and wears. Acrylic is a good material for socks, as it brings and maintains softness. Some other features of Dralon cotton: hypo-allergenic, easy to clean, quick-drying and odor-resistant.
