The shoe game: I think this could be so fun at engagement party, wedding reception OR anniversary!- the bride and groom both have one groom shoe and one bride shoe each, and they get asked these questions. When they think it's true for about the groom they hold up the grooms shoe, and likewise for the bride. (Only the bride and groom play this game. Everyone else watches- it is funny to see!!)
This one is fairly self-explanatory. Set this out on a table during your reception and let guests make contributions to your honeymoon. Not only is this a very cute idea, but people will enjoy helping you out with a little spending money during your honeymoon.
On each table at your wedding reception place a book or box with a note asking people to write a note to the bride and groom. The notes will be opened on the anniversary which matches their table number.
