I love an old fireplace mantel decorated for Christmas. My new house does not have a fireplace, unfortunately, but I plan to eventually get a fake one anyway.
This one is particularly beautiful:
There is an architectural salvage place nearby where I can choose from hundreds of antique mantels. I like this one, or something similar. I have not been there in a while but I think this will run around $1500 or so. Well worth it to preserve a gorgeous piece of history.
I can picture it decorated with greens and candles now. I can't wait to get my house!
