Hang curtains high and wide
Just because a window is tiny doesn’t mean it can’t be the focal point of a room. Create an illusion of width by using a curtain rod that extends three to six inches beyond the window frame on each side (this will also allow more sunlight to stream in when the curtains are drawn). Similarly, add height by mounting the rod four to six inches above the window frame, or halfway between the frame and the ceiling molding, advises Real Simple. To avoid an oversized look, hem the curtains properly. The fabric should either skim the windowsill or floor, or be cropped to about two inches above. These are the style secrets of people with impeccable homes.
Hang more than two curtain panels
When it comes to concealing an unsightly window frame, the more curtain panels you hang the better. Aim for three or four. That way, you can push one panel to each side of the curtain rod in order to cover the window frame, and use the inner panel or panels to cover the window itself. Here are the decorating mistakes that make your home look messy.
