I’ve learned the hard way that what is labeled as sock wool isn’t always sock wool. To date I have shrunk 4 pairs of socks by washing them in the washing machine following the instructions on the label… I now know from experience you can’t always trust the labels. This wool has never shrunk on me before and is now the number one choice of yarn for when I knit socks. The current pair is not for me. I get great pleasure knitting it being confident the person who will eventually get them can enjoy having them washed in a machine again and again and again and again….
