My family usually fills the house with decorations; fully-trimmed tree, paper chains on the ceilings, tinsel around the picture frames, clocks, etc, cards attached to ribbons and hung on the walls, fairy lights around the entrance hallway and bannisters... Since the full family is only usually together on the actual day nowadays, it's left until the morning before the decorating is actually done (my Christmas morning for the last few years has involved making those hanging card-display ribbons) but by the time everyone's arrived for lunch it usually looks quite festive!
