Sharpie Mugs that WON'T wash away

For Christmas this year, I received a lovely gift. There were 2 mugs, with mine and my husband's name beautifully written on them, and some hot chocolate. I could tell my aunt used a sharpie to write our names on them, and then baked them, (as is a popularly found on Pinterest.) I loved the mugs, and immediately used mine for some tasty hot cocoa. I put it in the dishwasher, and when I took it out, the design was completely gone! GASP! I was sad that she put all that effort in, and it just got washed down the drain. So I did some research, and found that OIL based is the key to getting a mug design with staying power. I bought 2 oil based sharpie paint pens and some sticker letters at the craft store, and got down to business. 

I am a lousy artist, so I used the sticker letters to guide me. I stuck them on the cups (an A for mine and a T for the husband's)

 Then made dots all around the letter, so that when I peeled it off, the outline of the letter would be visible. 

After I peeled off the sticker letter, I put the mugs in a 350 degree oven for 30 minutes, then let them cool completely before taking them out. 

I have put these mugs through the dishwasher 3 times, and the design hasn't faded at all, so I'm hopeful that it will last. I just love how they turned out!
