I needed a quick and easy present for one of my husband's aunties who recently became a great gran. I had a white mug stashed away in a cupboard
along with some edding porcelain brushpens. The tips can be used for precise lines and brush strokes. I dotted her initial on the front and wrote "No1 Great Gran" on the back and left it to dry for 15 minutes.
Then it went into a preheated oven at 180 Celsius for 25 minutes to bake and was left to cool down in it: Finished, dishwasher safe and to be filled with sweets.
