I don't know if your house is like mine or not, but this what my counter ends up looking like at the end of the day. Making me seriously envy my sister-in-laws drinking fountain she has in her HOUSE! Jealous.
Anyway, I've been trying to think for a while how to solve this. I even contemplated buying those expensive name cups at Toys R Us. But I would have to special order two names because they aren't common. Anyway, I saw this idea and knew I had my solution. I even had Staz-On but I had never used it. So, I picked up these plastic tumblers fairly cheaply at the big store that starts with W. And I stamped the names for each of my kids on three cups each. They get one cup a day. And the know which one is theirs. I threw the rest of the gross cups away. Yeah. #1 on my project list complete.
And yes, I did wash the cups and the ink really does stay on! (Hence the name)
Nice new, clean, personalized cups!
