Purple and Black Slouch Cap

I'm whipping up a cute little purple variegated slouch hat right now. The border (band) will be black. I'm crocheting it during TV commercials. I wish I'd had it yesterday when I was sitting in the bleachers freezing my buns off at an SCA event. Just that morning I had taken my hat out of my purse thinking I wouldn't need it on a nice sunny day. But then a breeze came up and the grass was wet from yesterday's rain and brrrr it got chilly.
