"We went with the pearl paper, which felt fancier than the matte. We also asked for the text to be in the 'pearl' color instead of the stock color, which felt really pink. We're very happy with the navy/cream color combo. Directions to our venue took up more room than expected. I was hoping to have a little more room to add a few more details. It would be great if they could print on both sides of the paper. We don't want to bulk up the invitations by adding another enclosure card, so we just skipped some of the details (like a link to the ferry schedule)."
"This card surprised me. I did not have alot to write but needed this for a short phrase. When I first ordered them, I thought they would look funny because of all the wasted space. Wedding Paper Divas centered everything and worked out all the details. I was very impressed. It did not look awkward at all."
