I had our RSVP envelopes printed and stamped out so that the only thing guests need to worry about is filling out the card and dropping it in a mailbox. But now I'm wondering should I include some sort of sticker for the envelope so people don't have to lick the back? I guess I probably wouldn't have put this much thought into it until covid hit and people started making a big deal out of those peel and stick envelope backs, which they did not have in the envelope color I needed. Thoughts? Would you think it is too over the top? Would you like it if someone included a way to seal the envelope?
