Ceramic pens/paints or sharpies and an oven.
You could make this as elaborate as you like with more colours, more text or patterns. You could even have circles of colour and so your actual paint will go in the spaces. It easier on a flat surface, painting onto a mug can be hard due to the round surface, but a bit of practice and also a cloth dampened with warm water will take away any mistakes quickly.
Hope you liked this little tutorial, these pens are so much fun for children to use too, so maybe it could be an Easter Holiday activity to keep those little ones busy if the rain keeps coming.
