I did initials, numbers, cupcakes, high heels, fleurs de lis, cookies from both girls' alma maters (one of which was mine, too -- Georgetown!). My favorite idea was a cookie with the Safeway logo -- where the birthday girls met when both families lived in DC years ago.
I packed them all with lots of bubble wrap and was so pleased to hear that they arrived, and to get some pictures from the party. Happy birthday Raine and Mamie!
