Felt Ski Hat With Ear Flaps Sewing Pattern?

I'm looking for a sewing pattern for a ski hat with ear flaps that will be made out of felt. All I can find are knitting patterns. Anyone know where I can find one? To give you an idea of what I'm trying to make here is a picture: http://metallixfaker.deviantart.com/art/Iguana-Hat-44733484.
