Indeed. Very good craftsmanship, sir!

...but those style bonnets always remind me of Cossacks... especially when they flare out more at the top.

EDIT: Upon looking at both of the pictures provided, I'm fairly certain that both bonnets have straight sides which are slightly larger in diameter at the top, and smaller at the headband; both look to have ribbon binding at the band, as well. I'd reccomend trying to increase at a constant rate, all the way up the bonnet.
