Thirty Before 30: Pinterest Project FAIL!! (project #4)

Ok, I decided to get crafty with this one! I found a pin that said you could decorate a mug with sharpies, bake it and the design wouldn't wash off.  I though it sounded awesome! If it worked I could decorate a mug for everyone for Christmas. I bought a mug from Kroger, decorated it, baked it at 350 for 30 minutes and I let it cool in the oven over night like the pin said to do and the next morning I took it out, washed it..... A day.....FAIL!!!! A lot of the sharpie washed off. Back to the drawing board!lol thanks lousy Pinterest pin!! 

FAIL......
