I have two sets that I put out each year. One is a complete set that my grandmother bought me when I was in high school. Several years ago my mom bought me a creche for it so that all goes under our tree each year. It's one of my favorite decorations.
The other set is a small glass set that my step-daughter bought for me one year. I put that in my window with some lights around/behind it. The lights just sparkle off the glass and it's beautiful!
