"Everything was wonderful. The design is beautiful; the colors came out wonderfully; and they came in a very timely fashion."
"Phenomenal feedback with customer service and the design department. They put the nicest touch on the card and it turned out even more beautiful than I imagined. Highly recommend!"
"This set totally sets the tone for an elegant wedding. It commands the attention of all of your guests and lays the path for a beautiful event."
"I used this enclosure card for a separate Reception information card. I wrote a line inviting guests to the reception after the ceremony, and included the address as well as the overnight accommodation information since the reception was host in the hotel we blocked rooms at. I also fit a line at the bottom of the page directing guests to our wedding website for more information. I worked with the design team to customize a font size in the middle of the page and they were very helpful to work with. They continued to send me revisions until it was exactly what I was looking for. I had a very positive experience creating this enclosure."
"I was concerned that this card would be too small to fit all of my information on it. However the customer service was wonderful in helping me fit everything on the front and back. The text size was not too small and it turned out great. I am so happy with how it turned out!"
