The Roll Brim Hat

So I wanted to make a hat that would keep me warm and be some what stylish. I decided on this pattern.
Only I wanted to use some yarn that I already had (Lagoon), yarn that was really soft and would be very, very warm. Keep in mind that I am a fairly new knitter. I was good and knit a swatch and made guage. So I set off on my quest. About 3/4 of the way through the hat I knew something was wrong. But I was determined to finish the hat, and finish it I did. I tried it on and thought "Hmmmmm, this seems a little big." But I wore it nonetheless thinking that we would adjust to each other, my new hat and I. Then a gust of wind almost blew my hat off and I realized I had a problem, a big problem. My hat was not only a little big, it was very big. Very, very big. The yarn I had used was indeed soft and warm, but also kind of stretchy. And I got lazy in my knitting and didn't keep my stitches as tight as they should have been. The result was my giant hat. I threw it in the washer, but all it did was get it clean. And if anything I swear it's bigger. It must grow when I'm not watching it. Because every time I look at it, it seems bigger. It now sits on the counter above the dryer. "The hat that ate Malmo..."
