Crocheting a Hat

You know that amazing friend I was talking about? Well, she inspired me to try to crochet something without a pattern. So I'm using leftover yarn to try to crochet a hat using only acquired knowledge from youtube. It looks ok so far, but its kinda turning into a hexagon... not exactly what I wanted, but it'll work! :) I'm started out by chaining 6 then I joined them to make a circle, then crocheted 2 in each stitch, then 2 in every other stitch, then 2 in every third stitch, and so on so forth. I'm gonna do that until it fits around the top of my head the just crochet all the way around and around until it's as "deep" as I want it. Hopefully it'll work! :)
