A wedding guest book is a special book used during a wedding ceremony or reception for guests to sign their names and leave messages for the couple. It serves as a keepsake that captures the memories and well-wishes from friends and family who attended the celebration. Traditionally, guest books are simple notebooks, but many couples now choose creative alternatives, such as photo albums, canvas prints, or customized cards. These unique options allow guests to express their thoughts in different ways, making the guest book a more personalized and memorable item for the couple to cherish for years to come.
