Gorgeous yarn! I've made a few crochet pots, bowls and so on; I'd recommend heading over to ravelry and searching their patterns. Many of them are free and there's everything from simple to complex. Happy making!

Hi! Acrylic yarn won't shrink and putting it through a very hot wash won't make it happy! What you could do in a case like this is sew a band of soft elastic inside the brim/edge of the hat for a bit of extra grip (and to stop it falling down over your eyes!)
