a little girl (I think a 7 year old) was having a birthday....she wanted to go bowling. Each of the guests received an invite and a funky pair of knee socks. Each girl coordinated her outfit for the party with the knee socks she received (and wore bowling).
I love this idea! My oldest will turn 9 (wow!) on her next birthday. She's outgrowing the little girl birthday themes...so my eyes are always open for creative ideas like this!
