I have a pair of Paper Denim jeans that I like a lot, but the wash is a little too dark, and they feel a little too stiff. I'd like to lighten and soften them, and maybe add a little distressing in a couple of places, but I'm not sure how to do it. Any of you have some good tips? Bleach? Sandpaper? I've also heard of Rit Fast Fade - has anyone tried that? Thanks!
