A window cornice is a decorative window treatment that can add elegance and depth to a plain-looking window. A window cornice can be used to hide the curtain rods and give your window a different style and a new look. There are ready-made window cornices that you can buy although it is also possible for you to make your own, using a few pieces of wood, wood glue, fabric and/or some wallpaper material to cover it and the tips below to show you how. Please read on.
- Measure the width of windows where you will place the cornices. Add another four inches to the width. The cornices should extend a bit from the window frame. The height of the cornices will depend on whether you want these flush against the ceiling or you want to use the top to display some items.
- Decide on the design. You can browse home furnishing shops for ideas or search the web for sites selling different types of window treatments for inspiration. If you only have basic carpentry skills and can only cut straight edges, a simple, rectangular box style is a good choice. You can make up for its plainness with some detailing later.
- Choose the pattern of the fabric or wallpaper that you will use to cover the cornices. The pattern should be neutral to blend will all the colors of your window curtains and your wall color.
- Cut the design from a half-inch thick plywood. You will be making a two-sided box with covered ends. Place wood glue over the thin edge of the front piece of plywood and place the edge of the other piece squarely against it at right angles. Use finishing nails to attach the two pieces of wood together. Add glue to the smaller pieces that will cover the ends of the cornices. Finish this by using finishing nails.
- Sand the sides of the cornice to remove splinters and smooth the rough edges. Measure the finished cornices and make a pattern on paper. Use the pattern to help you cut the fabric that will be used to cover the cornices correctly. Add a few inches of allowance to stretch the fabric over the edge and into the backside of the cornice and staple the fabric in place. Check to make sure that the fabric lies smoothly over the wooden surface.
- Attach small angle brackets or L-brackets to the wall above the window. Make sure that you measure correctly so that the cornice will be able to cover and hide the curtain rods and that these are aligned in a straight line. You can use just two angle brackets if the window is narrow and use three, one in the middle and one each for the corners if the window is wider.
- Place the cornice over the angle brackets and position it in place. Screw the brackets to the underside of the top part of the wooden cornice.
Darker fabrics will provide great contrast and framing to your window.
Dark colors will also be able to complement any other color. Check that
the angle brackets you will use are of the right length so as not to
extend too far over your window frame that will necessitate you having
to make a too-deep window cornice.
