Anybody know what felt hat stiffener is made of? You know, like the stuff you can buy at the Western wear shop for way too much money. Or at least it seems like way too much money. Could be that its main ingredient(s) is (are) expensive. But I wonder. If those ingredients are available in larger quantities for markedly less dough, well, I'd buy 'em. The standard answer is that it's some kind of shellac. But what kind? Where might I get some? And how would it best be prepared and applied?
