We just found out yesterday that FI's Godmother was very offended to not receive a Save the Date and didn't think she was invited to our wedding. Her and her husband are absolutely invited and I know we sent a STD to them. We didn't have any returned to our house so I can only assume it was lost in the mail. We feel awful that she thought she wasn't invited so my FI called her to clear it up (they played a little phone tag yesterday though so hopefully he'll finally talk to her this evening).
My question is, I have extra STD magnets left over so should I send her another one? The envelope and stamp would be different because I sent the rest in fancier envelopes than the ones the magnets came with and I don't have anymore of those or our photostamps. There's a good chance she saw the ones her family members received so she might realize that it's different.
