It worked like a charm! And even better, I messed up and was able to "erase" my marking with a little nail polish remover on a q-tip and redo my design. These mugs have been used multiple times, been put in the microwave and washed by hand without any change in the design.
I decided to make one a Harry Potter themed design...
and one a Sherlock inspired mug. :) (the scene this is from makes me cringe and giggle at the same time!)
I highly recommend this project if you're looking for some instant DIY gratification! Just remember:
- oil based paint Sharpie
- hand wash only
- keep your design away from the lip of mug (where you put your mouth to drink!)
