First wrap the hat around your head to see your best fit. If it is too large, it's no big deal. You can overlap the edges and knit it. Alas, if it is ...
I am a huge Wes Anderson fan, and his movie The Life Aquatic: with Steve Zissou is one of my favorites. The first time I watched it, I yearned (get it yearned) to have a hat like his (for Jacques Cousteau buffs, I know it was his hat first). To tell you the truth, the only reason why I wanted to learn how to knit was to make a Zissou hat. And yes, I am a boy which doesn't mean that I am girly for whatever. Knitting is for everybody!!!
My mom taught me the basics and hopefully a parent, relative, or friend can teach you how to knit if you don't know how. I think there are Instructables on it so they can help. For me, the book Stitch and Bitch really helped me.
Furthermore, this Instructable is for people who know how to knit and has been knitting for some time. This project is really easy so a noob can easily do this.
Step 2: Yarn and Needles
I used size US 8 needles (or 5.0 mm) and some red acrylic yarn. You will also need a yarn needle. It's a little plastic needle.
