This Hat looks like a Sea Shell, a Turbo Argyrostomus, that's what I found when I googled sea shell, sans the snail. I used a printed wool felt hood, next I'm going to block it with fur felt, You are right Cristina! Wool felt, complicated block? International Sign For NO insert here. The last photos are of what I did with the rest of the capeline I used for the Cocktail Hat with Quills. I used my old hand crank pinking machine. I love a good old machine with a hand crank.
