This yarn is best for tapestry weaving on small looms because it's not too thick yet very strong. It's made by Bockens of Sweden, known for their high-quality yarns.

Seine twine is a strong, tightly twisted yarn traditionally used in fishing nets. Weavers love it for warp yarn. 

100% unmercerized and unbleached cotton. 

12/6 means it is a size 12 yarn, spun with 6 strands. So it's very strong!
