Finding out who designed a room you found on tumblr is like a treasure hunt. But sometimes it's worth the effort. I love the Christmas decorations that David Phoenix used in his 2011 dining room at the Greystone Mansion in Los Angeles. Most of you who don't live in the big city can probably find most of the elements including pine cones, greenery, and berries in your own backyard. Sometimes being chic don't cost a thing.
