What you need to do:
Take your markers and draw cool designs, pictures or quotes on your mug. After you have decorated your mug to your wish, put your mug in the oven and bake it at 425 degrees Fahrenheit for 30 minutes. Leave your mug to cool inside the oven after you turn the oven off. Bring your mug out from the oven after an hour and cool it in room temperature for 24 hours. You can use your funky mug after a day, even create some more! The best marker to use for this project would be a Sharpie marker, which is available at most bookstores in the city.
