Sorry I’m a bit overdue to a DIY post… A couple years ago for Christmas, my husband’s sister really wanted a Harry Potter Grim tea cup. I had seen a ton of super cute How-To’s for making Sharpie mugs and figured I’d give it a try. Overall, I was pretty happy with how it turned out and my sister-in-law loved it!
What You Need:
A ceramic mug or tea cup (you can find cheap ones at Goodwill or the Dollar Store)
An oven and cookie sheet
Sharpie Oil Paint Markers
First, figure out a design you want to use. For this particular mug, I looked at pictures from the Harry Potter movie to mimic the Grim Professor Trelawney sees at the bottom of Harry’s mug. I also looked at pictures of different Harry Potter themed fonts to plan out the wording to write “My Dear, You Have the Grim” around the outside of the mug.
Once you have a design, it’s time to prepare the mug. Clean the mug with alcohol to remove any oils from fingerprints. Be careful to avoid touching the surfaces you plan to draw on. Once the alcohol has dried, start drawing away! I chose to use Sharpie Oil Paint Markers because they tend set better and last longer, but regular Sharpie will work also. Once you have the design on the cup, let it sit for a few minutes to fully dry.
Now it’s time to bake. Place the mug on a cookie sheet and place in the cold oven. Preheat to 350 degrees and then bake for about 30 minutes. Allow mug to cool in the oven. If you are particularly concerned about paint chipping off, bake for another 30 minutes once the cup has fully cooled to ensure the paint is completely set.
Once the mug is cooled, remove from the oven. Take this opportunity to make any paint touch ups if necessary and repeat the baking process. Once you’re happy with results, your cup is ready for use. I recommend hand washing to avoid paint fading.
