First about the hat. It'll work great for a man or a woman, and it is a simple repeating cable. You knit it in the round, so no seams to sew up!
You can choose your yarn weight. You can knit it in a thinner, DK weight yarn like Jorstad Creek's Hazelwood, or you can choose a thicker Aran/Worsted weight yarn like Jorstad Creek's Arranmore. Pick your color and yarn, and get started.
You may have noticed that this is the first Design we have from the BK Collective. They are a group of knitters and friends who have been knitting together and designing for years. In 2013, they decided to begin publishing patterns of designs they enjoy knitting under the BK Collective name. You can learn more about them here.
Stay warm out there.
