I like pretty much everything about this RSVP, it has all the info we'd need, i like the font, i like the hearts. I just wouldn't do the DJ song request thing, too much effort to then catalogue all of that.
LOVE this idea for a wedding invitation card. Add a Song Request card to send back with your RSVP then the music playlist will be what everyone wants to listen to! Especially because I'm having the hardest time deciding the music playlist
