I do Christmas up big! I stick with a traditional Victorian theme. I use White, Gold and Burgandy. Lots and Lots of garland! Make it as thick as you can using various types of greenery. I mix them and twist them together. Since this is so much work and takes a very long time (I have made over 190 feet), you will want to use the immatation stuff and just add real branches into it. Also anything 'real' that you can add is nice, like pine cones, berries, nuts, etc. Even some fruit like, pears. We start very early so use only the freshest branches so they don't brown too quickly. I also make all my own centerpieces. We really love the smell of pine, and miss it here so much (they even spray paint the trees here to our horror! LOL. Last year we had our old Christmas tree farm from back home (WA) mail us a real wreath! Oh what a joy. All this can get very pricey so watch for christmas stuff at estate sales and auctions. some times you can get some of real good quality for a great price. We lost "ALL" our Christmas stuff in a fire and had to start all over. We got a lot of good stuff at estate sales.
I do have a question for all you though. Last year we had a tree in each room. Now two of those rooms are guest rooms, do you all put christmas trees up in your guest rooms? just wondering..
