super cheap DIY to get custom curtain rods, cheaper than wmart, nicer, b/c you don't have that "bump" that adjustable rods give. (and those usually look cheap too, if they show. these look much more professional)
imagine the possibilities for using spray fabric paint on an old piece. create a simple diamond shaped stencil from tag board and the slightly random spray will give you a faux ikat pattern. Or spray over an old floral and let the pattern come through in places.
