I have used spray starch to good effect. Of course, the hat can't get wet, after. And test spray to see how tha fabric react to it first.Is there a spray on stiffner for felt, and if so what's it called?Geiamama, you hat is lovely, I'm going to have a go at that Pathe idea too!
Thank you all for posting pictures and tricks for the Vintage Vogue hats. You have all done a wonderful job! I'm currently trying to decide if I want to make the C or the D hat.
