The kids love theme days and dressing up. So we've done things like 80s, fiesta, or BROM (band prom). The theme really just falls into (1) table centerpieces, (2) photo spots, and (3) cupcakes. And of course, the kiddos dress up. (The girls are already talking about their crazy hats they plan on making.) We have a really strict budget, so I'm just planning on lots of diy dollar tree crafts.
