Premium Silk Sock yarn is a high-quality blend of 21-micron superwash merino wool, silk and nylon, with a count of 4/17. The merino fibers have been specially treated before being spun to enable it to be machine washable. The silk content makes it beautifully soft, glossy and temperature balancing. The knitted fiber features a wonderful elasticity, while also keeping its shape. This yarn is perfect for socks but can equally be knitted into scarves, shawls and accessories which will feel soft and silky next to the skin.
