Christmas tree ornament
I just finished decorating my Christmas tree and I have to say that some of my most treasured ornaments are the photo ones of previous Primary classes. One that I especially treasure this year is the one of a class of (then) CTR Bs. At this present moment 3 of the five children pictured are serving missions. Take a picture of each class. Mount them on cardstock cut into some type of Christmas symbol and I guarantee they will be loved and appreciated anything else you can think of.
