Consider making a window out of a scarf. We chose a black scarf with fringes and sequins to dress up a window with pre-made wall corbels.
Another idea is to use a tablecloth. We selected a ruffled lace tablecloth that still lets in some light. Since the tablecloth already has a finished edge, no sewing was required. We attached the window treatment using a standard cane, finial and wall corbel. Once the rod was installed, the tablecloth was simply draped over the rod to create a lace curtain effect. Experiment how to drape the fabric to the desired length. If you have enough fabric, you may want to "smear" the bottom edge of the curtain on the ground below the window.
Fabric shower curtains are another option, and they are easy to install as they are finished at the top with ready-made grommets that can be used for hanging. Simply feed a thin coffee rod through the grommets to serve as a curtain rod to create a wavy pleat.
Dress up a window treatment using costume jewelry adapted to make tie-backs. Using an attractive inexpensive shower curtain and costume jewelry can create an attractive window treatment for very little cost. A similar effect can be created by using a sheer fabric with a pre-finished border. We use a stamp to create star patterns in the material, and we gather and fix the material with a piece of jewelry. The stamped material was hung from a rod and collected at the bottom.
Lastly, consider using a ruffled and patterned bed sheet to create an eye-catching window treatment. In our demo, we simulated a three-pronged curtain fold by folding and pinning the sheet at 6-inch intervals, and stapling the material to a piece of wood used as a support.)
