Sharpie + Dollar Store mugs + Bake at 350 for 30 mins = easiest personalization ever. You can even use super cheap mugs from the dollar store to create gifts or party favors. Just draw on the surface of your mug and bake it for 30 minutes at 350 degrees.
Maybe instead of buying expensive cups, I can make some custom ones with cups from the dollar store and sharpies. I'll never have to worry about them not matching my kitchen, BC I can always make more! And they'll have sentimental value.
