Green Mountain Spinnery suggests substituting their new New Mexico Organic (estimated availability September 2007).

From the Green Mountain Spinnery Knitting Book: “fine wool from sheep grazing the transmission line rights-of-way in New Hampshire is spun into yarn using our GREENSPUN method. Controlling vegetation in this quiet, pastoral way reduces the use of herbicides and petroleum-powered machinery. Perfect for baby clothes, shawls, or projects worn next to the skin.”

Greenspun is Green Mountain’s name for their process that uses no petroleum or chemical products in the preparation and spinning of the yarn.
