Ours is pretty traditional. A green tree with mutli-colored lights and lots of decorated glass ornaments. We use silver beaded garland and our tree topper is a fiber optic angel in a beautiful white gown.
Our tree skirt is a white one with a Precious Moments nativity scene on it and below our tree is a nativity set that my grandmother gave me when I was in high school and a creche that my mother gave me several years ago. Around the edge of our tree skirt, my Dh has a Christmas train running.
