I have a white kipling bag ( this is my favorite brand of bags and I have dozens of them) that I bought ages ago and didn't like it. Toooo white and shiny. So I finally got up the courage and started drawing on it. YES with a black marker, lol. It is supposed to be permanent when dried, though I have to be careful when I am drawing as it is wet for a while and smudges easily. This is the beginning of my drawing, I will be covering the whole front of it eventually, one bit at a time.
