If your thing is a contemporary design, you should look for classic and modern pieces which never go out of style, as for instance Lucite tables and leather-made white Barcelona chairs. Learning how to decorate living room may require a bit of documentation, but room design ideas are always a useful experience.
Pastels are basically a staple for French decor along with patterns and wood accented furniture. Rather than covering your walls with a toile or rose laden wallpaper, consider painting them pastel blue instead. Suddenly all the blues in the room will feel tied together and more styled than you ever thought it could be.
