We teamed up with Earthstar Farm in Montana, a small, regenerative, organic farm tucked at the foot of Big Mountain’s snowy slopes, to bring you Big Mountain Cormo Worsted, an incredibly special undyed 100% Cormo wool yarn. Every stitch connects you to a happy flock of gorgeous sheep that thrive in the high mountain air!

• All of the wool for Big Mountain Cormo Worsted comes from Earthstar Farm’s small, beloved flock of pasture-raised Cormo sheep who love their Rocky Mountain lives. The farm’s practices are time-tested, gentle, and humane, and the wool is combed and spun into yarn by an artisanal family mill in Wyoming. The whole process, from shearing to milling, happens just once a year… This is truly a small-batch yarn!

• The Cormo breed is a cross between Corriedale and Saxon merino, and their beautiful wool is prized for its exceptional softness, elasticity, and lightweight warmth. Cormo sheep were first bred in Tasmania, Australia in 1959 and were imported to the United States in 1976. Earthstar Farm’s flock are the direct descendants of those first American Cormos. The deep-cold winter climate of the Montana Rockies helps these sheep grow extra fine and thick fleece to keep them snug without weighing them down… Music to knitter’s ears!

• Big Mountain Cormo Worsted comes in five undyed shades, a naturally beautiful palette straight from the sheep. The farm carefully breeds for three pure, unmixed colors: Swan, a soft creamy white; Raven, a rich, complex brown-black; and Merlin, a warm, taupe-y moorit color. Two mixed grays, Eiderdown and Dove, complete the range and round out the collection with subtle complexity.

• A round, 3-ply yarn at a classic worsted weight, Big Mountain Cormo Worsted knits up quickly, and you’ll love this earthy yarn’s springy bounce, clear stitch definition, and velvety next-to-skin softness. Use it for all kinds of wonderfully sheep-y accessories and sweaters that highlight the wool’s natural beauty. Explore our Big Mountain Cormo Worsted knitting patterns for some amazing ideas!
