"Our enclosure card for our wedding invitations turned out great! I loved that we were able to completely personalize it to say everything we wanted to on one card! And it saved us money so we didn't have to get several separate cards to give our guests the information they needed! The design specialists were great in putting little finishing touches to really complete the look. My fiancé and I were very happy with them!"
"This card is beautiful like the invitation. I love how versatile the wording and title is for this card. Easy to edit, great help from the reviewer at Wedding Paper Divas! Thanks!"
