Hehe, I tend to just butcher it! The way my hair sits, it doesn't matter if it's uneven. I just take scissors to it when I'm out of the shower. I'm really bored of it at the moment though, and think I'm going to take a chance on a hairdresser.
If you search, you'll probably find some advice on cutting your own curls on here though. I think the CG book has a chapter on it, so I'm sure there'll be some advice on how to do it properly!
