The only dying I have done is on corn husks, for corn husk dolls. It was really fun. I used beat juice and yarrow for the red and deep yellow I needed. I have used the color remover before. That is fun to fix a white blouse that accidently got into a red wash.
I did buy some rit dark navy dye last week to re-dye my jean bermuda shorts. I haven't tried it yet... Kinda scared. LOL!
