The big thing for me is the size of the tree. I know in Europe there are many countries that typically use tabletop size trees. I just LOVE a full-size, floor to ceiling tree that becomes the unrivaled focal point of the living room. I prefer long needles to short needles. I love a variety of lights (both size and color). The pictures above are very beautiful, classic trees, and I love them. Ours is never quite that fancy though. Also, I must have a star on top that lights up.
Two years later, and I still feel the same. I love the variety of everyone's traditions!!
