What the heck is a CVM?
CVM stands for “California Variegated Mutant.” Yup, for realz. CVMs are a colored strain of Romeldale sheep.
Romeldales are an American breed of sheep developed in the early 1900s, from a cross of Romney rams and Rambouillet ewes. They have always been quite rare. In fact, for many years, almost the entire population of Romeldales lived on a single farm, Stone Valley Ranch, in California. And the entire clip of wool from that flock was sold each year to Pendleton Woolen Mills, in Oregon. Like most commercial wool operations, Pendleton was not interested in colored wool, so colored lambs were culled from the Stone Valley flock. But in the 1960s, Glen Eidman, a sheep breeder who was working with Stone Valley’s owners to promote the breed, decided not to cull a colored ewe and then, later, a colored ram. Eidman bred the two colored Romeldales, and dubbed the resulting sheep California Variegated Mutants.
From the beginning, Eidman bred CVMs with handspinners in mind. But even with a small group of spinners enthusiastic (very enthusiastic) about their wool, the numbers of both Romeldales and CVMs dwindled without a breed association to promote them. The Livestock Conservancy, a group that champions rare and heritage livestock breeds in the US, formed a breed association and registry for Romeldales and CVMs. Even now, though, the Conservancy lists them as “critically” endangered, which means that there are fewer than 200 Romeldale/CVMs registered annually, and that the worldwide population of these sheep is likely less than 2,000 total.
Sheepspot's very own CVM yarn—with 280 yards of two-ply, woolen-spun goodness in every skein, made from the wool of a flock in (where else?) California—is on sale now.
