With record lows sweeping the nation this week, the word “doldrums” has taken on new meaning as we all bundle up inside and do our best to stay warm while the winds howl outside.  There’s no more classic way to cozy up than to do so in front of a blazing fireplace, and while we’ve shown you plenty of ultramodern freestanding fireplaces, today we thought we’d stick with tradition but maybe look at a modern version of it.  So, we’ve rounded up ten modern fireplace mantels, all perfectly framing the blaze within but doing so in an artful, even progressive way. Roast those chestnuts and enjoy those s’mores… with the winter officially settled in, you might want to stock up on logs and kindling and settle in yourself.
