I was thinking maybe I should do STD cards but I kept telling myself I was insane to be thinking about the party this soon. I'm glad I found you guys because I've now convinced myself to do it.

As someone else mentioned, if you go through the trouble to send STD cards, your guests will know that you're going all out for the party. And you can get on their calendars first! I plan way ahead and as I've found out, most people are not like me and we always end up with way more people at the party than expected because no one believes is RSVP-ing anymore. What's up with that??
