I made the invites to look like a stadium ticket. On the back I put address label stickers that I printed and had listed where she was registered and to whom to RSVP.
The baby was due on 10-3-13. That is where the section, row and seat numbers come in. Also, I don't know much about NFL football but I made the garland with the number 13 just because that is the year of the baby's birth.
