"I love this trifold save the date! It's very unique and gives opportunity to use several engagement photos! Also, the design team worked with me to include the text that I needed (that did not originally fit) and to change the colors to match my wedding colors!"
"We got our save the dates in the mail today. I was shocked to see how amazing they turned out!! We are doing a wedding on a budget and saved ton by doing our save the dates on our own. They look as though we spent a lot of money to have them custom made. I ordered the pearl shimmer paper and envelopes and WOW! it really makes it pop. The cards are bigger than they appear in the pictures. Paper quality is nice too! We are super happy, we placed another order. You won't be disappointed."
"I love this card! Just wish there was a spot to include more information, such as travel reservations and/or accommodations."
