Nature Spun is perhaps the most versatile wool yarn available. Each of the 80 colors is available in worsted, sport, fingering, and chunky weights. Knitters especially love Nature Spun for fair isle and color work. Our U.S.-grown wool is soft enough to be worn next to your skin. Nature Spun's triple ply and 100% wool makes it strong enough for weaving, and it's available on cones.
