With our first mill-spun yarn we’ve stayed true to our roots, using springy Cormo wool from a pair of ranches located in Wyoming and Montana, and tinkering with the spin to make sure we’re getting the most from this lovely fiber.

We worked with our mill to create a special method of fiber preparation, one that marries woolen and worsted processes. The result is a unique yarn with woolen-spun’s airy loft and worsted’s strength. Springy, lofty, and with a substantial hand, Stone Wool Cormo offers crisp stitch definition and elegant texture in knitting.

The yarn blooms in the soak and can be knitted in a wide range of gauges for different fabrics. We recommend needles size US 6 - 7 for hard wearing knits, up to US 9 - 10 for knits with drape.

Our color palette features 21 colorways, and each color family is dyed to a gradient in 3 shades, a light, medium, and dark.

Spun in Wyoming from 100% American Cormo wool. Dyed in Maine.
