These would be an ideal prezzy especially when it comes to Christmas and you have heaps of people to buy for. They'll feel the love with your DIY skills.
So basically buy some mugs and some sharpie pens. Go nuts - write and draw all over them.
Once your mugs are a work of art put them in the oven for 30 mins on 180.
Then your done - see that was easy!
BEWARE: You can't put these in the dishwasher so treat with care and handwash.
