Handspun single ply 100% wool. Natural color, undyed yarn finely spun from roving on a spinning wheel and wound into a ball with a manual ball winder. The 'natural' color may vary slightly from ball to ball. I call this batch 'Heather Brown' because it has flecks of white and varying shades as well as some gray. Averages 60 grams/2 ounces.
