This is a PortFiber exclusive - a special top blend of our own making! 60% British Southdown, 20% British Shetland, and 20% tussah silk makes for a great spin for socks, mittens, hats, and everyday sweaters. Southdown brings softness and bounce and the natural brown Shetland adds a that variegated look. Neither of these wools has a ton of luster, which is where the silk comes in! Expect a staple length of 2-4 inches and a micron count between 28 and 31. This fiber is not super ideal for wet felting.
