How tree-rific is this guest book alternative? Bad jokes aside, we love this creative idea to commemorate your wedding day and those who helped celebrate with you! Have your guests sign the tree ring using black sharpie markers and encourage them to share a special story or memory they shared with you! This idea is perfect for spring and will totally complement an outdoor wedding! After all the festivities, you can display your signed tree ring in your home or in your garden to always remind you of your special day!
