How to Make a Bed Crown Cornice

A bed crown cornice is a decorative feature -- similar to a fancy valance -- placed on the wall above a bed. The cornice can be made of wood, polystyrene foam, or medium-density fiberboard covered with fabric. To make a simple bed crown cornice, cover moulded polystyrene foam cornice pieces with fabric -- no saw or sewing machine required.

  1. 1

    Measure the area over the bed with a measuring tape. Decide if you want to use one 40-inch piece of cornice or two pieces of 40-inch cornice to make an 80-inch cornice. If you need a 60-inch cornice, purchase two 40-inch cornices and cut one piece in half. Purchase polystyrene cornice pieces at a craft, hobby, or fabric store. The easiest kits to assemble come with the polystyrene foam piece and wall mounts.

    If you need to cut the cornice piece, measure where you need to cut it and draw a line to mark the spot. Use a serrated knife or hacksaw to cut the foam. Glue the two pieces together and let dry completely.

    Lay your fabric good side down on an even surface. Place the cornice piece upside down on the fabric. Hold the fabric on the cornice piece and flip both the fabric and the cornice piece over. The good side of the fabric should be facing up with the cornice piece underneath. Using your fingers, press the fabric into the two slits at the top and bottom of the cornice piece so the fabric is taut across the front.

    Turn the cornice piece over and tuck the fabric into the slit that runs lengthwise on the back of the cornice. You will have excess fabric at both ends. Gather the fabric of one side in a tight bunch toward one end of the back slit. Twist the fabric tight and press it firmly into the slit.

    Gather the fabric on the other end and twist the material tightly. Press the fabric firmly into the slit that runs lengthwise at the end of the cornice. Turn the cornice piece over and ensure that the fabric is taut with no wrinkles. If there are wrinkles, take the fabric off and recover the cornice piece again, making sure to stretch the fabric tight.

  6. 6

    Measure the wall over your bed where you want to put your cornice. The wall mounts should be 6 inches from the ends of the cornice and no further than 28 inches apart from each other. Mark where the wall mounts should go. Attach the wall mounts. Hang the cornice on the wall mounts. Using a level, make sure your cornice is straight.

Tips and warnings

  • Add accents to your cornice. Attach panel curtains that hang from behind the cornice, or use a skirt accent, a roman accent, or a balloon accent. Add lace, cords, or tassels to the cornice to dress it up. You can also change the fabric on your cornice for holidays throughout the year, or to represent seasonal changes.
