I'm totally in need of some Vuittonducation. So how long does it take for the patina to change. I know that sun and handling speed things up, but my bag is already honey colored and I DON'T want a dark brown handle EVER. So if I guard the leather now, and keep it in the dustbag when not in use, keep clean hands etc etc... I should be able to keep it this color for how long. So I suppose my summary question is... How long did you have your bag before significant patina changes. Thanks!!
