I veer towards the more modern when it comes to aesthetics and these are my favorite types of Christmas decorations as evidenced by my pinterest board.
Unconventional Christmas Trees. I still want a full-sized Christmas tree to hang ornaments on but I love the takes on other trees that can be used either in an office, or a kid room or if you really are into that sort of minimal Christmas look.
Taking classic ornaments and modernizing them to fit your look. I love this whole ombre paint the balls thing in black and white.
