Decorating without a Christmas tree can be a bit challenging, but it's certainly possible! You can still create a festive atmosphere with other types of decorations. Consider hanging stockings on the mantle or by the fireplace. You can also decorate the walls and windows with garlands, lights, and other festive decor. You can even set up a mini nativity scene with figurines or a small Christmas village. Don't forget to add some delicious holiday treats, like cookies and hot chocolate, to make the season even more special.
