"I customized this program with a custom color to match my wedding colors and chose an edge trim to make it really unique. They turned out perfect!"
"I am very pleased with these programs. They fit all of the information I needed them to. I used them just to name the wedding party instead of the wedding ceremony because we're having a very basic ceremony and people generally like to know who's standing up there. The paper is very nice, just like the invitations. The only thing I was a little disappointed about was the top of one of our names was cut off just a little bit. It's not a huge deal and I'm sure most people won't even notice but of course I did because it's my wedding. I thought they would catch something like that while editing them. The previews I saw were too small to see it. Other than that I love the product that I got."
