Try and stick to a common theme that will look organized and coordinated together when holiday decorating. Do this to avoid looking put together last minute or like it wasn't thought out enough. Try keeping your color scheme to just a few colors so it doesn't look overloaded with too many colors. Be sure to make the area smell holiday fresh by putting out scented candles that are coordinated with the theme where people are going to be. By doing this the area will stay smelling cheerful no matter what other smells may be brought around.
Being Safe While Decorating
When you are holiday decorating keep in mind that things might be knocked over by accident. You should make sure that all the decorations are out of any area where they can cause a fire or harm someone like by a fire place and in walkways. Keep any candles or light decorations away from any flammable objects. You can put decorative flowers in the middle of tables as a centerpiece to give the area a more lively appearance. You can also add decorative plants in corners and by areas where it might look a little barren and in need of some holiday cheer.
