Great plan! Looks good. It's amazing how much gunk on handbags can actually just be picked off. I picked off what looked like white paint or liquid paper off that trashed courier bag I washed yesterday. Came right off.
I bought the same wallet from Goodwill recently only mine is whiteish and patent leather and I must admit I don't know how to rehab it. From what I understand marks don't come out of shiny patent leather easily. It is cute and not too awful anyway, just a few little marks here and there. I love the lining.
Thanks! Yes, fingernail picking works on a lot of things (not just guitar strings...

I've avoided patent leather so I don't have any tips for you on that. The lining is beautiful, I agree!
