The seafarer’s scarf’s pattern is rather easy. It is designed to bring out plain yet beautiful yarns well, without distracting from it.
I recommend bulky yarns (the one I used is stunning, if you can get your hands on it - bulky yet soft) and a 6,0mm needle.

The pattern can be used to any measurement you like. I recommend knitting up a swatch and then figuring out how many stitches you want. I used 33.
