Good for you and the environment! These are fibers leftover from making other yarns- the soft too-light fluff, the bits that otherwise would have been lost to the waste stream - and made this handy, durable, and surprisingly soft high quality yarn. Universal calls this 85% recycled cotton/15% recycled polyester blend "clean cotton" because it's a yarn you can feel good about using. Easy care too - machine wash - warm, do not bleach, tumble dry.
