This pattern uses a single 100g ball of yarn. The three I’ve listed are three different yarns that I’ve made this in now. The King Cole Chunky Glitz uses a 5mm hook, and the Sirdar Hayfield Chunky and the King Cole Chunky Tweed needed me to go up a hook size to a 5.5mm. The pattern is written using US terms. It roughly follows an 8-row repeat, with adjustments to allow for buttonholes where needed.

There is a shorter version (which fits my skinny neck) and a slightly longer version of the pattern on the website, both workable out of a single 100g ball.
