This classic sport/DK weight 100% wool yarn is a perfect basic that everyone needs in their stash. The GOTS certification is much more comprehensive than Oeko-Tex 100 - it means that everything from animal welfare to pollutants is checked. The production of the yarn is environmentally friendly, and everyone involved is ensured proper wages and working conditions. The raw wool comes from Argentina, and no mulesing has been used. The wool is spun and dyed in Italy.
