Watkins Printing was a professional and quick printing vendor. We designed our own invitations as a Photoshop file (they have both blank and customizable templates on their website), and we got a lot of compliments on them from our friends and ...family. We had several hundred invites printed, and the price was still reasonable, and they got our order to us within a week of us giving them our final quantities and files.
I do wish Watkins offered more invitation sizes--we chose a two-sided Z-fold format which mostly showcased our gorgeous engagement photos with very minimal text, and the 5x7 size when multiplied by the folds (the full invite size when unfolded was 17"x5") was a little bigger than I would have liked. Still, I was definitely pleased overall. And for those who may not be confident in their own design skills, Watkins has friendly and talented members on staff who are more than happy to help you create something you like.
