I picked up this hat at. The craft show yesterday. The seller let me in on her pattern and sewing directions and I was able to replicate it using sweater scraps from my old mittens.
The top is made from a tear drop shape. The brim can be from a pike shaped rectangle where the concave side matches up with the corvette of the drop shaped top. The pont is then sewn down near the brom and may be embellished with a button or layered flower.
