I didn't think it'd turn out as well as it did to be honest. If you are going to try it I have a few pointers: -Make sure your cover your nose and mouth with something and do it in a well ventilated area. -You should do about 3-5 coats of marker with a least a 10 minute gap between coats to get good coverage (I did it over a a few days) -Make sure you plan what you are going to do, and visualise it. Once it's on, it's on and there's no getting rid of it. -Don't get any on your clothes or hands because it is very hard to get off your hands, and pretty much impossible on clothes.
