The curtain and Shelf
Here is an idea of window treatment married a petite drapery to a display shelf. It appeared in a kitchen, but is here adapted to a bedroom.
Buy two ready-made wood brackets (the kind that can support a shelf) from a lumberyard or Home Depot. Mount them on either side of the window, making them flush with the top of the casing (or higher, if you want the illusion of a taller ceiling). Cut a shelf as deep as the brackets and set it on top. Edge it with molding, if desired. Paint the shelf and brackets white.
Now set a slim tension rod (from any hardware or fabric store) between the brackets. Float a lightweight, floor-length sheer from the rod. Set a few lovely objects or vases on the shelf. It will make a handsome display and draw the eye up, implying height.
