One Beer features a distinct rib and garter pattern, which really stands out in a tweed yarn. I love the boldness of the garter and how the crown naturally "stars" in at the top. One Beer is easily modified for depth or width, and instructions are given in the pattern. I also think this one can be pretty feminine if knit in a girly color!

I think this hat would work just as well in a worsted merino, or other wool, as it does in a tweed. Have fun and experiment with yarn and colours. Always check your gauge and adjust needle size if needed.
