Anyway, on with this weeks Tried and Tested...
It is a pretty simple craft really - all you do is draw on your design using the Sharpies (you can use pencil first if you like) and then bake in the oven for about 30mins. When finished turn the oven off and then leave the mugs in there to cool down. Et Voila!
So if you are looking for a way to keep your design on mugs then my advice is forget the Sharpies and go for some proper mug paints available from most craft stores or pop along to one of the many great pottery cafes.
