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.
Buy a mirror. Put letter stickers on it. Paint over the whole thing. Peel off stickers. (use canvas instead of mirror. Paint canvas what color you want your letters to be first, then letter stickers, paint over, peel off)
