One of these days, I'd like to try out this adorable mini balloon-in-a-box invitation. They remind me of the balloon save-the-dates, but are possibly even cooler.
Apparently, you'll need special 5" balloons, which will hold the helium for a couple of hours. This means they'll need to be hand-delivered. But that's fine by me. Seeing reactions is the best part, right? :)
