- 1). Use the tape measure to measure the length of the window cornice. For those that are 24 inches or less you will need to attach the cornice in two locations on the ceiling with screws. For those longer than 24 inches, you will need to add one set of screws for every 12 inches of length. For example, you will need three sets of screws to attach a 36-inch long window cornice or four sets of screws to attach a 48-inch-long window cornice. Round up to the nearest division of 12 when calculating the number of sets necessary.
- 2). Make two small marks on the top, inside of the window cornice. For a 24-inch-long window cornice, measure inward 6 inches from one end and make a mark. Make another dot at the 6-inch mark, 1 inch up from the first. Measure 6 inches inward from the opposite end and make two more marks in the same manner. For window cornices of different lengths, measure 6 inches inward from each end for your first marks, and then add two more marks in the same way every 12 inches.
- 3). Drill a hole through each mark. Hold the window cornice against the ceiling in the location you would like. Use a pencil to make a mark at either short end of the cornice and a dotted line along one long side. Lay the window cornice aside for a moment.
- 4). Use the pencil marks to draw marks on the ceiling that coordinate with the location of the screw holes on the window cornice. Drill a small pilot hole through each mark on the ceiling.
- 5). Hold the window cornice against the ceiling, and line up the holes in the window cornice with the pilot holes on the ceiling. Insert the screws into the holes in the window cornice and screw them into the pilot holes in the ceiling.
