This post for a framed wedding menu at the Ruffled wedding blog has a ton of cool possibilities. If you are comfortable with Microsoft word, you could pretty much use any background to create these. First you'd want to find the picture you want to add, then import it to add the border (here's a tutorial for word 2007). After that, you can split the page in half to make it fit into the frames mentioned in the Ruffled post. There are plenty of tutorials on how to work in word on the Microsoft How-to articles page.
