Thanks everyone for your comments!
mello_yello_jen: Because I'd heard horror stories and personally know people who'd sent their bags to Chanel and were disappointed with the results... Apparently the leather felt very different/worse? Every one of them regretted dyeing it in the first place... I initially just wanted to clean up the straps, but I was pretty impressed by the photos on lovinmybags site so thought I'd give repainting a try.
