Close off one end of a room with a drape. There's no need to add a physical wall to create a separate space. A drape works just as well, and an added bonus is the warm cozy feel that all the fabric creates when it is pulled closed. Place a chair, chaise, or window bench behind the curtain and relax.
To get this look, use a ceiling rod bracket from Country Curtains with a 3/4" rod, add rings and hang a drape or drapes.
