so late yesterday I finally got all 170 invitations in the mail! such a huge relief, I can't wait to start getting replies back!!
here is a picture: they are plum and lime green and tied with a white/plum ribbon(pic is crappy one from my phone)

and then everything is tucked in the back, directions, accommodations, RSVP card etc:

and I forgot to take a pic, but my favorite part is on the RSVP envelopes, it say "Soon to Be Mr. and Mrs. Smith" love it!!
