Welcome to Hidden Brook Fibers. We raise and process fleeces from a variety of fiber animals on our farm in Stow, Maine. Some fiber is processed and dyed completely on the farm. Fiber for yarn is sent to local mini mills. Products can be purchased by email and from our website. Our fibers are also available at two fiber festivals. Maine Fiber Frolic in Winsor, Maine in June and The Common Ground Fair in Unity, Maine in September.
