For invitations, we purchased our daughter a Spiderman outfit online. We took a variety of pictures to choose from and then ordered customized birthday cards ($1/ea) with her as Spiderman on the front in his infamous pose. The invitation reads, (front of card) "An Invitation from"(inside of card) Your friendly neighborhood wall-crawling, crime-fighting Super Hero...Spiderman! A.K.A. (our daughter's name) and birthday details followed. This turned out to be fun because the parents couldn't figure out if it was really our daughter in the Spiderman outfit or not.
