As part of their Shave ‘Em to Save ‘Em Program, the Livestock Conservancy had Deb Robson create a series of heritage sheep fiber profiles.  They are available for download on their website.

Fiber Artists, not sure which heritage breed sheep fiber would be best for your next project? Shepherds, want to provide your breed’s fiber information to your wool customers? Our Heritage Sheep Breed Fiber Profiles, written and compiled by fiber author Deb Robson, detail each breed’s fleece weight, staple length, fiber diameters, lock characteristics, natural colors, and best uses for fiber projects.

Thank you to the Center for Craft for their generous grant, which makes these Heritage Sheep Breed Fiber Profiles possible.
