Here are two lovely Keepsake Marriage Certificates that I have posted for you to download for free. The files are in PDF format.
One of them is bright and colorful with a touch of whimsy and a poem. I used a landscape orientation and a purple border with a multi-color chroma rose brush design that I made using Photoshop.
The other one is done in portrait orientation and is black and white. The frame is an intricate vintage frame.
It looks to be Victorian and even a bit Steampunk!
The vintage frame graphic I used to make this certificate is from The Graphics Fairy website. I love that website!
The fonts I used on the intricate fancy frame certificate are more formal looking than the fonts used on the colorful whimsy keepsake certificate. There is a quote from scripture at the bottom of this lovely keepsake marriage certificate.
(be sure to save them as opposed to just viewing them via your browser PDF viewer)
