The bedroom is in some ways the most important room in the house. It is the sanctuary away from the troubles of the world, the ultimate escape from day to day life. Behind closed doors in the bedroom, problems can be forgotten. To create a setting for restful slumber, think about what colors and styles produce the greatest happiness and peace of mind. In your bedroom, you can have the off the wall decorations you've always wanted. The bedroom is private, so the interior design of your bedroom is all about you.
