Thanks. I typically don't use any dyes or color creams. I've found that a bath, use of a combination of conditioners, and brushing with a horsehair brush will restore most bags. Sometimes corners or edges need extra treatment, but vintage
Coach bags made of glove-tanned leather that have been dyed through the hide are amazingly resilient. And if a vintage bag has a little character, I'm ok with that, too. It just means they have a story. (I am again working on a bag that must have been scratched by a cat. It must have an amazing story.)
