Sharp mugs

I found a tutorial on Craft Gawker for decorating coffee mugs with sharpies!! So I went hog wild. I created one of my own on a plate with quotes from the first chapter of the first Harry Potter book (The Philosopher's Stone) and went over in orange all the words that were HP related for extra emphasis. I love emphasis; sometimes you can never place enough on things that matter!
Then I baked it at..350? I think for 20 mins. :)
