What will you need:
Mug ( I got mine at Ikea)// Sharpie
First, I would recommend to make a design of what you want to put on the mug. I found that it was easier to have a bit of guideline to help you space it out.
Then it's time to put the design on your mug! Just be careful not to smudge the letters (I'm left handed so that's usually a problem..).
Then to make sure your design stay on the mug, bake it in the oven for 30 mintues on 175°C. It's not 100% gurantee that it will stay on, but I found that it holds up quite well if you only hand wash the mug.
And that's it! All there's left to do now is wrap it up and surprise your dad on father's day!
