My sister sent out the invitations for my shower with three big errors-left off my best friend as a hostess, got two of the other hostesses names wrong and wrong date for RSVP. Sent out the invitations and now we're sending a corrected invitation to everyone with an insert. I'm thinking the insert should be light and maybe say "Oops! Please disregard the first invitation. My assistant was on vacation." Or "Oops! We left off some very important information. Please disregard the first invitation." Which sounds better or any other ideas as to what the insert should say? Thanks!
