One of the easiest ways to add texture to a room is by using inexpensive bamboo shades. (This apartment owner added the ribbon trim herself. This little project is on my “to do” list for our living room.)
What I love about bamboo shades besides giving rooms another layer of texture, is that they can work in casual and dressy spaces, alone or under other window treatments.
Bamboo Shades can be used to filter the light coming into your room. When privacy is needed, consider adding curtains as another layer. The combination really works well.
