Ok, thanks guys. It's not the canvas or the leather. It's the hardware hanger. I don't dare to oil it eighter..
Ok, thanks. I suppose this is a problem with the LV straps.My speedy b strap did this too. It was annoying. I ended up selling the bag (not because of the noise though). I doubt you can fix it, I think it's just the way the hardware rubs together when it moves.
