I saw a beanie like this when I was out shopping one day so I decided to try it out! It turned out to be really easy! All you have to do is crochet a beanie but don't reduce all the way to close it up at the top. Leave a little "tube" and start crocheting up and then start reducing again, but not as quickly. I crocheted about five rows and then reduced by just one. Crochet five rows, reduce by one, crochet five rows without reducing again, reduce by one again, etc. If that doesn't make sense send me an email and I can give more detailed instructions!
