This fiber is Manx Loaghtan wool.
Manx Loaghtan is a rare British sheep breed. This top is a natural medium brown, which gives you an intense depth of color if you dye the fiber. The fiber is about 30 microns, so it isn't supersoft, but should be excellent for outerwear, mitts, hats, etc.
This fiber can be spun any way you like for a wonderful yarn. Please take care while hand-washing the yarn or crafted item.
I try to photograph colors as accurately as possible. Please keep in mind that color varies from monitor to monitor--what looks right on my screen may not be the same on yours!
