Decorations strung up in the windows.
A candelabra in the bay window.
Christmas tree, obviously!
Christmas cushions.
Garland on the door frame. Fabric heart hanging on the door handle.
Two nisser (Christmas elves) that sit on a little chair to the side of the fireplace. Toying with the idea of a poinsettia on the other side this year but I don't like to buy them anymore as they're never very happy in the long term. Otherwise I'll have a little faux tree there.
Little porcelain candle holder houses in the fireplace (5 of them to make a village). This year those are going to be upstairs in our bedroom, with battery operated candles for safety, so I'll just leave our lantern in the fireplace instead.
A selection of things to sit on the cabinets/bookshelves: little porcelain angels and candle votives, little porcelain snowman and woman. Gold Christmas trees, set of three. Little fabric Christmas mice. One of those tea light holders with spinning decorations. Might also put an advent candle holder on one of the shelves but it would have to be purely ornamental as I can't light candles on that shelf.
A string of lights on the television unit.
A candle holder on my coffee table. A bowl of nuts on DH's coffee table. A bowl of huge pinecones on the console table - I use these as a vehicle for Christmas scent, just a few drops of essential oil every few days.
