I've never done that because we store our wrapped presents under the tree ahead of Christmas day, but I love the look of a train traveling around a tree. Putting village pieces around it would be fun too! Of course, in my house, the villagers would be squashed by Catzilla. ;-)
Hi Amanda-- Train sets under the Christmas tree bo back in my memory to my childhood. There's always excitement in the eyes of young children as they watch up close to the train going clickety-clack around the track.
