I apologise if I'm repeating a topic, but couldn't find it anywhere else... I have a hat decorating workshop in two (TWO!!! ) days, and the only hat I could find that was even vaguely suitable had two problems: 1) It's white (I need it black or wine, or at least a very dark green or even purple). 2) It has glue marks where someone had a ribbon attached. Is it possible to dye a felt hat without having to re-form it? It feels like reasonable percentage wool felt, but there is probably some rayon in it. I guess the glue marks can be covered if they won't come off... Also, with the class in two days, I bet I wouldn't have time to dye it tomorrow and have it dry in 24 hours... At least, not with a decent depth of colour? Can anyone give me any pointers? The hat's not vintage, I'd say about 20 years old, give or take. Thanks!
