If you are into either Victorian or country, I saw some great trees for you. The Victorian one is decorated in ribbons and glass balls ( a little on the pastel side, but you could change it to your fav. colors) and the country one has boots, sleds, bears, birdhouses, even a cowboy Santa! One year I made my tree all snowflakey and snowmen without any Santa type ornaments at all. It looked very pretty with blue lights and a snowflake/snowman tree skirt. How about a my favorite things tree? Yes, I know it's a recurring theme of mine, but the both of you could make crafts and place them on the tree. If your roommate paints, maybe they could make some of those ornaments they sell at Michael's. Heck, even a nautical tree with sailboats and seagulls. Or go the extra mile and make it a pirate tree.
