Yaaay, doodle mug! :) Why not, right? From paper to porcelain! :)
I'm super chuffed with how this turned out, but I have to admit that I didn't use a sharpie in the end. I used a porcelain marker instead, which needed half an hour in the oven to be fully cured. Now it can even go in the dishwasher, which is pretty awesome actually! :)
I didn't end up using the sharpie because I needed to find the right type. But without being in the US (where sharpies are plentiful and affordable) I decided not to risk the longevity of the project and go with a specific pen designed for porcelain.
The effect was sooooo good - I'm really pleased with it. I think this might be the beginning of much more crockery doodling. Oh my, the possibilities are endless! Hoorah!
