The hook size is N 13mm
This scarf is easy to adjust to your tastes, if you like long scarves chain more at the beginning. You can probably get 2 skinny scarves out of one skein, so make one for you and one for a friend. Or you may make a wide scarf just for you, by repeating the rows (in order) until you‘re out of yarn. This simple scarf can be also made in any gauge yarn you’d like.
