How should I decorate my living room wall? Can you provide some tips and ideas?
First, you need to consider what type of style you wish to convey in the entire living room. This will dictate how you should decorate the living room wall. If you have a "statement piece" such as a large plant somewhere in your living room, design the wall as a counterpart to it.

You can decorate a living room wall with far more than a painting, although having a painting or other artwork be the central focus is not necessarily bad. Consider a variety of wall art including wall sculptures, mirrors, clocks, floating shelves, plants, and bright, bold colors.

Draw a few sketches out on paper or a computer program before you start to get a general idea of what you want to convey on the wall. And most importantly, have fun!
