How do I clean Sharpie marks off of a leather couch?

Take a look at the book the Queen of Clean, I know something is in that book, I would try some vaseline, or baby oil, or murphys oil soap, or dove soap, don't try to scrape it off you will ruin the leather, if you cannot get it off, my guess would be to get another sharpie marker in a lighter color, then go over it with a marker the color of your leather couch
