I saw the hat Little Rock wore in the movie Zombieland (just caught it on cable and it's a riot! I don't normally like gory movies but this is more funny than gory). Needless to say I HAD to have one, even though it's nearly 100 degrees now!
I have offered up the pattern free on my blog, or on Ravelry here
if you want to fave or queue it. In bulky yarn on 10 & 10 1/2 needles it works up in a day or two.
Mine are made with Lion Brand Wool Ease Chunky. Pattern has 2 decreases.
