"We bought these to compliment the Dappled Glade Signature Wedding Invitations, and they performed perfectly! We used the card to send out information about RSVPing, the reception site, and a note to see our wedding website. We ended up changing the Header font to match that used in the text body, and centered all of our text. I would highly recommend ordering the 8 free sample invites from WPD - it comes with a paper texture information booklet that is extremely helpful!"
"These came out beautifully. I used them as hotel and directions cards. I absolutely loved them- they went perfectly with the invitation."
"We used the Directions card for special requests from the Bride and Groom. We wanted to use a different font from the invitation and that was no problem. WPD designers are very accommodating and quick to respond. The enclosure card turned out great!"
"These are adorable cards, perfect for that extra memo for your guests. They are on the smaller side, so try to limit the length of the message. I used these for our wedding website address, and just wish our website address we used was shorter so it didn't look like it was running off the card. Otherwise I love these cards!"
"We used this enclosure card to include some additional details for our guests. This card is the same size as the rsvp card, which is my only negative comment. I would have liked if it was slightly larger to give some variation in sizes. Also, this card came with free envelopes which I thought was strange - in most wedding invitations this card has hotel information (or something similar) and would never need to be mailed back. Nonetheless, I accepted the free envelopes and hope to use them casually."
