Luggage Tags are an excellent idea for save the dates, placecards, and favors. They’re especially appropriate if you’re having a destination wedding, but I think they’re something practical that everyone will use and love.
If you’re using a luggage tag as a save the date, you can print your wedding information on one side of the insert showing through the window, and leave blank lines on the other side for the guest’s name and address.
