Lil B discovered my big black Sharpie marker today. I don't know how he found it but he created some artwork on my coffee table. I would've taken a picture but I was busy googling permanent marker on wood. There were many suggestions. Hairspray, rubbing alcohol, trace with dry erase marker and wipe off with black board eraser. Some of the suggestions didn't apply because my wood is unfinished. I used the Magic Eraser and was able to get most of it off. It's alright. It's the whole reason why I went with the furniture I got. I wanted something to be able to withstand the abuse.
