A pelmet is a four-sided box that mounts above the draperies. It usually covers the curtain rod. Adding pelmets above your window treatments creates a dramatic statement. Often pelmets are designed and decorated in formal styles and paired with expensive and operational lined curtains. This combination adds to the layered look of a well decorated room. The box can be painted, padded and covered with fabric.
Measure the width of the window and add 20 cm (8 inches).
Cut two 2.5 x 15 cm (1 x 6 inch) boards to the width measurement. Cut two boards 15 cm (6 inches) plus the thickness of the wood. Although wood may be called 2.5 cm (1 inch thick), most timber's actual measurements are smaller. Use the smaller or real thickness measurement.
Label one long board the top and the second long board the front. Stand the top board on its long side edge. Apply a bead of carpenter's glue along one long side of the top board. Align the front board so the side of the front board presses into the glue and the ends and edges of the boards line up.
Nail through the side of the front board into the end of the top board with a finish nail gun. Space your nails 20 cm (8 inches) apart. Wipe off the excess glue.
Apply carpenter's glue along the short edges of one side of the top and front boards. Align the small wood piece to the side (it will only fit one way). Nail through the side piece into the ends of the top and front boards. Use two nails per board. Wipe off the excess glue. Repeat for the second side.
Add L-shaped metal brackets to the underside of the top board to mount the pelmet box to the wall. Use taller boards for taller ceilings. The distance away from the wall should be enough to cover the curtains and hardware.
