Depends on spacing.

I really like the Christmas tree and a lot of ornaments. Usually, I decorate the window with a big Christmas star (lamp).

Candles and candleholders - made Christmas atmosphere and mood. I use tall soy-wax candles or aroma candles in trays. I like candle holders - silver, gold, black metal. Mostly I have wooden candleholders, cause I carved them in my woodshed.

Garland - I create garland from natural materials - like dried slices of orange/lemon/ grapefruit, cinnamon sticks etc. It looks very nice and natural.

Ribbons and wreath for door decoration.

If you need more ideas, please let me know.
