Have you gotten to know Laurelknits' wonderful BFL Silky Sock sock yarn yet?
BFL Silky Sock is a sport-strength sock yarn that is a combination of wool, silk and nylon. The yarn is smooth and silky and has great stitch definition. One 100g skein is enough for medium socks up to size 39. In addition to socks, the yarn is also great for e.g. scarves and other accessories.
Laurelknits is a small Finnish company whose founder, Laura, dyes the yarns by hand in Helsinki. The color map of the yarns is unique and the shades are easy to mix.
