The pattern is a FREE Ravelry pattern, called THE JACQUES COUSTEAU HAT. It's a CLICK HERE
free pattern, however, when I made a copy/paste of the URL...it gives me an internal server error 500. So, if you are a Raveler, you can find the pattern in the hat patterns section, and if not a Raveler, I will be happy to email anyone the hat pattern. As I said, it is a FREE PATTERN. It is knit in the round, casting on 140 for a man's version, 2x2 ribbing for 8 inches, then beginning the unique decrease process.
The yarn is JO SHARP SILKROAD DK TWEED, leftover yarn from my brother's bomber jacket. I made this hat for my brother, to complement his bomber jacket.
However, when my DH saw this hat...he said, "I like this hat better than the other ones you've made me! Boy, this is so cool!"
So I gave it to him.
It's doubtful that my brother would wear a knitted hat anyways.
He has longish curly hair, which he painstakingly primps and styles...and I've never seen him wearing anything but a baseball cap on a bad hair day prolly.
