Large wall in interior present a big challenge of decorating with the right style. However unique ideas for large walls can greatly improve the interior mood of the space in a very short time because of the visual attention it gets easily.

This will break down the wall into small compartments so that each individual unit is obviously smaller than the total size of the wall. This can be achieved by using a chosen wallpaper design.You can also use curtains to break down the large volume of the wall. Simply divide the length of the wall into 3 or 4 sets and use curtains as a way to sooth the heavy volume of the wall. While selecting the curtains keep in mind the overall decorating theme.
