If you know how to crochet in the round, you can make a hat.
The easiest way to start crochet in the round is to chain 2, then make 6 single crochet in the second chain from the hook. This is more single crochet than will reasonably fit in a single chain, causing it to curve around. This will create the beginning of a small circle. The first stitch and the last stitch you made will be touching. Make your next stitch in the top of the first stitch. For the second round, you will want to make 2 stitches in each stitch of the first round. Since the first round was 6 stitches, the second round will be 12.
From this point on, you only need 2 basic concepts to create a hat shape.
1. If you want to flatten out, add stitches as your circle starts to buckle. If you add only a few stitches it will create a rounded dome shape. If you add more stitches it will be flat. Just add them as you like.
2. When you want to create the sides of the hat, make no increases. This will create a tube. The tube should be about half of the hat. This will cover your ears.
