A window cornice box can make any window look luxurious. They are a very effective way to add extra interest to any window. Making a window cornice box is very simple if you have all of the right tools and materials. It should be a project that you can complete in a couple of hours, with enough preparation.

Step 1 - Planning

The very first thing that you need to do is plan the design of your window cornice. There are many different types of design you can choose to use. You can have a window cornice that is covered in fabric, or choose to stain or paint the window cornice instead.

Measure the width of your window and add two inches either side so that it's easy to fix the window cornice into the area around the window frame. Decide how tall you want the window cornice to be.

Draw a life size drawing of the window cornice on a sheet of paper and then cut it out using your scissors. This will allow you to offer it up against the window frame to check how the finished window cornice will look. Be sure about the fit of the window cornice before cutting the wood. Cutting paper will be much easier than cutting the pieces of wood if you make a mistake.

Step 2 - Cutting Wood

Now you know the dimensions of each of the pieces that will make up the window cornice, it's time to cut the wood. The wood can be cut using a normal saw, or alternatively, with an electric circular saw. Make sure you cut the wood carefully to ensure that you don't cause yourself any harm. You should wear goggles and gloves.

Step 3 - Finish

You will now need to consider the finish of the window cornice boards. There are a number of different finishes possible. You might like to fix fabric over the whole window cornice, or you can stain or paint the window cornice. If painting or staining you should probably wait until the cornice is assembled and installed. This will allow you to paint over the filled holes.

Step 4 - Covering in Fabric

Covering the window cornice box in fabric is the most popular option for finishing the window cornice. This can simply be stretched over the frame and stapled in place. An optional extra includes placing foam under the fabric to make it cushioned and look more luxurious.

Make sure that you stretch the fabric so that it doesn't pucker or look strange. Also, if the fabric has a pattern in it, make sure that you keep the pattern straight.

Step 5 - Attaching the Window Cornice

Now the window cornice needs to be fixed to the wall. This is very easy, as it can be fixed using screws. You might need to use drywall screws if fixing into drywall.
