"Loved the card only problem is that I thought it was just the front decor and plane back side, it is a card you can open if you want to have someone at wedding paper divas write something inside the card for you be very specific because mine came with the writing on the back/outside of the card which looked really weird. But nice card if done correctly"
"These thank you cards came out exactly the way I pictured them! I chose to do all navy blue printing because that is my wedding color. They came out great! Wedding Paper Divas has done my save-the-dates, invitations, rehearsal dinner invites and now thank you cards - love them all!"
