From Clark Creative:

"The theme of the entire wedding is woodland. The bride and groom love the outdoors and wanted to bring that love for nature into their wedding day. They are using birch tree sticks as center pieces and slices of the tree to act as tiny plates and coasters. Since it is a summer wedding, we made sure the tree on the invitation was in full bloom, so it didn't give too much of an impression of fall. The heart with the arrow and their initials in the center adds a playful and youthful element to the design."
