Last year on my way home from a business trip to NC I stopped by Starbucks and found these awesome personalization mugs! You use the provided pen to write/draw whatever you want on the mug and then bake it for permanence.
I'm sure that there are cheaper ways to do this little project and whether you buy the Starbucks mugs or buy some dollar store mugs...I highly recommend this fun little project for any married couples that drink hot drinks. :) So fun! So sweet! :)
Disclaimer: These mugs have held up super well! They are still perfect though they have been used, hand washed, and dishwasher washed MANY times! :)
