I plan to hand write all of the addresses on the main envelope of the wedding invitation, but has anyone used any quick ways to address your own address on an RSVP envelope? We have a ton of wedding themed address return labels of our own address.... but I don't know if it's even possible to use that as the sending address. I have no problem writing my own address out on 100 RSVP envelopes, just curious what others have done. TIA!
