Family Tree Sign is 7"x11" or 10.5”x16.5”. It is made of 3 layers. The front and the back will be made of walnut while the tree will be made of birch. You may have anywhere from 3-18 hearts. If you need more than 18 hearts for your design, I suggest doubling the names of couples on a single heart. The sign will have a hole in the back for hanging purposes.
