I'm sure you've seen these if you spend anytime on Pinterest. Designing your own mug for yourself or as a gift is fun and cheap. I'm thinking of doing some as Christmas gifts. Finally got around to trying this out for myself.
If you google "Sharpie mugs" you can find numerous tutorials on how to do it. Supplies/Directions are easy:
White ceramic mug
Draw what you want, bake at 350 for 30 min. Let cool, hand wash only.
Could it be more easy? I think if you wash it in the dishwasher though, the design will fade faster or come off completely.
I copied a design I saw on etsy. It always makes me lulz.
