This cross can be used as a Christmas tree ornament that you give to your kids or grandkids or can be used as a Christmas card from one family to another. Either way, you will want to engrave a special message on the back for the person or family that you are giving it to. An example: To Our Special Grandson Luke, Love, Grandma and Grandpa, 2016. This would be a 4 line example of what can be engraved on this cross or any cross in our collection. Just type this in the box that comes up when you select the Engraving for Back option. At the end of each line put a forward slash "/". That's all there is to it.
