This yarn is spun from a fiber blend that includes some from the sheep at Star Gazing Farm. It is a perendale sheep breed, blended with mohair (which is from a goat). You can read some interesting information about the perendale breed at wikipedia: en.wikipedia.org/wiki/Perendale_(sheep). The fiber was so much fun to spin. The dark gray blended with the white to create a barber shop pole effect on some of it, but I also got plain white or plain gray on other parts. I decided to ply it as a three-ply.
