I just finished filling out my invitations and was on the phone with my parents, and they wanted to make sure I had stamps on my RSVP send back cards. I had a moment of panic, because I completely forgot about this. Is this a huge deal? Should I go and readdress new envelopes so I’m able to stamp the rsvp cards? I was reading a forum from 2017 and people were all saying it’s super tacky. Any suggestions for an honest mistake 🥲
