You have various possibilities for decorating a wooden cornice box. Some designers paint their box using elaborate stenciling, while some upholster it with material. An upholstered box lends texture and heat to the window, and also you may stylishly customize it using complementary material from various other patterns in the room. This simple, no-sew job is easily finished in a hour and takes only a few essential tools.
Place carpet tape on all four edges of the front face of the cornice board. Place a very long strip lengthwise down the middle of the front face of the board. Strip off the protective covering from the rug tape.
Put on the upholstery foam to the face of the cornice and the rug tape, allowing the foam to overhang all the sides of the front board by 1/2 inch. Trim the foam using scissors, if needed. Press the foam on the rug tape.
Ascertain how much material you’ll need. First, measure the front part of the cornice from right to left, then measure each of the side panels to the right and left sides; insert these totals together and add another 6 to 8 inches. This measurement indicates how broad your fabric piece should be. Measure the front part of the cornice from top to bottom, and measure the top shelf insert these totals together and add 6 to 8 inches. This measurement indicates the necessary height of your fabric. As an example, if your wooden cornice is 36 inches wide by 18 inches high and the panels and also upper shelf are 6 inches broad, your fabric bit will be 56 inches wide by 32 inches high.
Put the fabric, right side down, on a big table. Place the cornice face down on the cloth. Center the cornice; use the measuring tape to locate the specific center, if needed. If your fabric pattern is striped or contains symmetrical patterns, line these up, too.
Position your helper so that the top shelf of the cornice faces him. Instruct him to securely pull and pull the cloth up and above the cornice’s upper shelf and then about to the inside wooden frame. Begin at the middle of the cornice and pull the fabric taut, so it doesn’t develop wrinkles. Staple the fabric to the inside of the frame every 4 to 6 inches, then working your way from the middle of the cornice to the right side, then from the middle to the left.
Repeat this process for the base of the cornice. Working from the center, have your helper pull the cloth tightly up and above while you staple it on the inside of the frame.
Staple the sides of the cornice at the exact same manner. To neatly staple a corner, then fold the end of the fabric, as though you were wrapping a present box. Staple the fold.
