I was able to test this hat recently for Comfy Cabana. It is called Scallopeanie and is made up of a very unique set of stitches and is quite adorable when worn. You can either end it with a scallop or a striaght border. So it would work for both boys and girls.
You can find the pattern HERE on Ravelry and follow Comfy Cabana on FACEBOOK for more patterns. :)
