The yarn is a bit odd - the details above say it should be 170 metres per 50 grams for the DK, but mine says 200 metres per 50 grams, which is the equivalent to a sock weight. But it does say DK on the label - 22 stitches per 10cm. My gauge is coming to 21 stitches per 10cm and it is quite gappy, so around the shoulder I have reduced to a 3.75mm when I get to the shoulders to reduce it stretching out there.
