My daughter Megan made these adorable printable invitations for her sister-in-laws baby shower. There are a variety of diaper colors to choose from so it made for a very colorful and happy invite. The free download includes instructions, thirteen different diaper colors, printable envelopes, printable safety pin (or you could use real safety pins) and printable invitation.
These fun little diapers could also be used as a party favor to add to the theme of the shower. Slip a candy bar or wrapped cookie into the diaper instead of the invitation and send them home with your guests.
