The Birlinn Yarn company is a spin-off of the Hebrides Sunhill croft. “We are proud of the Norse and Hebridean heritage bred into our sheep. Hence, we twine this creative yarn into everything we do.” The company advertises that its yarn is “from seafaring sheep” because the sheep are ferried back and forth to pasture. Colors are beautiful. No superwash, no fillers, all UK sheep, all the time. Note: The patterns section has marked links to Ravelry.
