Our 2-ply Wool-Nylon Blend Yarn is a blend of 50% wool and 50% nylon. The nylon adds durability, while the wool adds softness and warmth. This blend will also keep the yarn from matting during use or wear, adding to the life of your knitting or crocheting project. The yarn is a Sock yarn (Superfine) and is recommended to be used with a US needle size of 1-3 or US hook size of B-1 to E-4. The gauge of the yarn is 25 stitches and 33 rows per four inch on US size 3 needles. The 100g (3.5 oz) skein comes with approximately 467 yards (427 metres) of yarn. Please note that our Wool-Nylon Blend Yarn is not pre-shrunk. Washing Instructions: Our yarn can be machine washed with an initial water temperature not exceeding 40C (105F). Do not use bleach. Lay flat to dry and do not iron. A machine dryer may also be used on the lowest possible temperature setting. Available in 100g (3.5oz) and 6LB skeins.
