Elizabeth and Steve's old school Nintendo wedding featured Marios and Luigis and Thwomps and Fire Flowers galore. One tiny detail that we especially loved was their message in a bottle guest book. They offered theme-appropriate colored Post-Its, pens, and small bottles so that guests could write them a note for the future. I guess being married is a little like being on an island sometimes. You've got to get advice from off shore sometimes.
They chose three different anniversary years so that guests could choose when their note was read.
Here is the text from their signage, in case you'd like to do something similar for your guest book:
Like wine, love only gets better with age. Instead of a guest book, leave us a message in a bottle and help us to celebrate years in the future.
So write it, roll it, and pick the anniversary year that you want us to read. Choose one date or do all three!
Here's another example from Megan and Dave's rustic forest wedding:
