This step you can implement for an elegant Christmas decoration. The main one is to determine the color theme for Christmas decorations. Choose a calm color like brown, green, gold. Avoid colors that are too flashy and collide with each other.

Put effort into the main decoration. Keep it focused and neat. As much as possible hide the complexity such as tree lights and Christmas decorations. Only pairs of furniture and decorations are truly meaningful. Choose a calm and classy style. Cleanliness is certainly the main thing. and lastly keep it simple.

Hope this ideas help you.
