I have one the the patchwork pieces from a few months ago. And like a lot of bags it has leather trim all over it. It had a few scuffs when i bought it, be now that ive used it the number has tripled. I tried gently rubbing one the spots with water. that got the scuff out but left the area a little darker. do you brilliant ladies have any ideas??? (* just a side note. the leather is light brown) Thanks!
