Hello! I have an old millinery book and in it, they talk about making a hat block out of stiffened willow esparterie. I really like this idea because I can't afford blocks at the moment and I don't necessarily like cutting up styrofoam. I know that willow is pretty much impossible to come by these days, so I was wondering if there are any hat foundations still available which might achieve the same thing? Hope it's not a silly question! Thanks for your help.
