Christmas Decorations

Christmas season is coming:) I'm excited. Did you start to prepare for Christmas? I've browsed magazines many times and created some decorations, but I haven't got any good idea to decorate them yet. We don't have Christmas tree as the following pictures (from the magazine 'House Beautiful') and won't buy it this year, but somehow I want to decorate our lovely rooms. Should I go to shops and get some decorations?
