"We loved this version because we were able to select different pictures that told a story about our "Save The Date" for our wedding. We got them as magnets and are very happy with the way they turned out."
"We just sent out these Save the Dates and loved them! The photos looked great, the size was exactly what I expected (postcard size), and it was nice to not stuff envelopes. There is a downfall to no envelopes though--handwriting addresses. It would be nice to have that option for printing. The only complaint I did have with the design is the "To:" on the back was over to the right so far that it made it very hard to write out people's names. Overall, it was a great design and worth every penny!"
"I loved how easy it was to upload our photos on the template. The simple elegance of this save the date is what caught my eye. I wish there there was more opportunity to insert extra text without going through a designer (the only thing I would add). Overall, I'm very satisfied!!"
"The save the date cards were delivered very quickly and everyone complimented how beautifly they were. I will definitely be doing my invitations with them!"
"Love the quality of Save the Dates, only down side is that the post office ruined half of the postcards. I would recommend regular Save the Dates with envelopes."
