My fiancé and I have finally decided we want a very small intimate wedding. We want to only invite our immediate family and best friends. We plan on sending invitations for a "surprise party" for my birthday to all of our other family and friends for afterwards and when we arrive we plan to announce at the party that we were just married. We still want little invitations that basically say you're invited to a secret wedding but don't spill the beans, but in a cute way. Any ideas on wording?
