"I really liked this response card. We made some revisions to the card. They came out perfect. We just wanted to know who would be attending. We took out a couple of lines and had them adjust the print. They made the cards exactly as we ordered them. Very easy ordering process."
"These response cards are just beautiful. We had a destination wedding and used these for the reception back in the United States. They captured the beach theme perfectly. I received so many compliments on these, they were a huge hit!"
"Great little card to send for RSVPs, only thing that would make it better is if they could be postcards so you could save on shipping"
