This is a blended yarn that I did with the help of Yolo Wool Mills in Northern California. Th wool comes from some of my sheep as well as friends' sheep e did a joint project to ye and blend the wool with a bit of silk and mohair. I know it is mostly wool but not the exact percentages. It is a two ply yarn would knit up well on size 5-7 knitting needles depening on what you want to make. The yarn is a lot lighter in color than the photo shows.
