We are doing a castle shadow box where you sign your name on a heart and drop it into the castle to display it on our wall. Another idea that my best friend did was she set up a photo booth for the guests and the person running it printed a strip for you to keep and a strip for the guest book they were putting together. They’d glue it in and you could sign and write a message under the photo strips. At the end of the wedding the bridal party hung out and we all went through them and it was really fun and cool to see what people did and wrote.
We'll be doing wine bottles. It will have labels on them that say 1 year anniversary, 5 year anniversary and 10 year anniversary. And a sign saying that we will open them at their respective anniversary and think of those who celebrated with us on our wedding day.
