Shopping for curtains is all about function and fashion. Window curtains can help to filter, reduce or block outside light, frame a beautiful view or obscure a less desirable view, reduce noise, provide privacy, highlight architectural features or camouflage structural irregularities, and add an insulating layer that both enhances cooling and heating efforts while reducing energy consumption. Sheer and semi-sheer window curtains may be used alone, layered or used in combination with solid window curtain panels – much depends on the look you want to achieve. Curtain construction must also be considered – should you have a large or ornate curtain rod, grommet top curtains may be the best choice, or reversible rod pocket curtains with a large hem that can accommodate a bulky rod. Alternatively, you may prefer to use curtain clips to hang your window curtain panels. Seek a simple, rustic look or want to open your windows to enjoy more of the view – a valance alone may be the ideal window treatment for you.
