Not all wool is created equal. Understanding wool grades helps buyers appreciate why premium pieces command their prices and what distinguishes exceptional rugs from ordinary ones.
Wool quality depends on sheep breed, climate, altitude, and diet. The finest rug wools come from sheep raised at high altitudes in harsh climates, where animals develop denser, longer-stapled fleeces for protection. New Zealand Merino and Himalayan Highland wool exemplify these premium grades.
Fiber length matters significantly. Longer fibers can be spun into stronger, more lustrous yarns that resist pilling and maintain appearance through decades of use. Short-stapled wools, while less expensive, produce fuzzier surfaces that deteriorate more quickly.
Lanolin content affects both feel and durability. Premium wools retain natural lanolin oils that create soft hand-feel while providing inherent stain resistance. Over-processed wools lose these beneficial properties.
At Eastern Mills, we specify wool grades appropriate to each product's purpose. Our heirloom-quality hand-knotted pieces use only premium long-stapled wools, while our production lines select grades balancing quality with accessibility.
