Fun wedding invitation enclosure idea: include a favorite quote
I love the idea of including a little keepsake with your wedding invitations, such as a small printed quote. If you're paying to have your wedding invitations printed on nice paper anyway, why not get a small piece of art out of the deal? You and your guests can frame it or put it on your tackboard or refrigerator. It can serve as a nice reminder for your guests, without having your actual invitation framed and hung in their living room.
Plus, they're just a pretty addition! Many photographers I've worked with on styled shoots print quotes to style and include in the invitation photos, and it would look amazing in real weddings as well!
