I think the cups make the perfect activity for those first 15 slow minutes of a kid's party, when guests are starting to arrive but you're not in all-out party mode yet. Then, as the party gets going, each kid will know which cup is theirs. But I'm also going to keep these in the back of my mind for those times I've signed up to bring supplies to school for classroom parties. What a smart sit-at-your-desk activity that's still very cool, thanks to the cute but weird monsters on them. As all monsters should be. You can find these fun color your own paper cups at Oh Happy Day's party store online. Fair warning: you can spend hours looking through all the amazing party finds she has there.
