Need some advice from anyone what has maybe done this... I've got a black canvas Gucci bag (it's NOT logo print... just black canvas) and it's faded over time. I called my shoe/bag "God-like" cobbler, and he said he could dye it, and would put a protective sealant on it, but the dye might still rub off. So, I'm hesitant to do it for fear that I will: 1.) end up ruining a shirt by wearing my bag (think- large square on my side) 2.) never wear the bag again b/c of maybe ruining another shirt! Has anyone dyed a bag? Any problems?
