I objected strongly to losing the first hat, and guess what, someone listened to me!
Here is her version, even better than mine, possibly because she used cashmere/cotton twill from Michaels Fabrics for the outside, how luxurious. I love the contrast lining and how she has turned it over to form an edge on the outer brim.
I am pretty sure there will be many more of these hats in our future - or maybe I can find the more recent Patricia Underwood hat pattern, I'm sure its somewhere in my pattern collection.
