I think a buffet is ubiquitous with the Fourth of July. Big crowds, lots of food, and - often - potlucks mean one large table in the middle of the room somewhere. Cover it with something fun and clever and make my new tablecloth! This is so easy your kids can help (mine did) and feel proud that they contributed something to the celebration.
I've even put together a little step by step video to show you just how easy this is!
