Since the party only lasted an hour and a half, and was loaded with activity, it seemed silly to spend much time contemplating food choices beyond the cupcakes. We just made sure to have several drink choices- which of course included water with customized water labels- as well as juice and soft drinks. We also bought some snacks (ginger snaps, pretzels, etcetera) and made some pimento cheese sandwiches, putting them in pretty vintage bowls and white servingware.
I included a tutorial photo for the cupcake flags (second photo, above). Four different versions of flags were created in two colors. I wrapped the flat 'flag' around a toothpick with a paper top (this helped the rubber cement adhere to the toothpick), using a bone folder for a crisp edge, and voila!, flags were done. For those who aren't computer savvy, this could easily be done with pretty patterned scrapbook paper for the same effect.
