80% Superwash Merino 20% Nylon Yarn. Two plies are twisted tightly together to produce a very soft and springy yarn. This yarn is slightly plumper than our original Deluxe sock yarn (which has 4 plies) and just as soft. The 2 plies make the yarn slightly bumpy which helps the strands of yarn hold together against each other making it great for colourwork and lace work. 100g/400yd
