"I am completely in love with this RSVP and the final product is beautiful. However, they left out a line that I requested even though I added it before approving the final product."
"Designer was so attentive and quick to make any changes or alterations we asked for, and made things look even better than we had planned! So many compliments!"
"I was able to change the highlight color to the exact color to match my bridesmaid's dresses. These cards were super cute, modern, and chic!"
"They came out perfect. I had asked them if they could take the food part off and make the accepts and decline bigger and centered. They got back to me the next day and sent me a proof of it centered and bigger font. I loved it and I also got it within a week after proof reading it."
"These RSVPs matched the invitations nicely! You can print on the back so I used this to add 4 lines and asked the guests to list the names of who is coming (makes sure you don't miss anyone). I also asked if they were staying the night at our block of hotel rooms - welcome basket early notice! I put a note on the front to make sure they looked on the back. Simple, classy and coordinated!"
