Draperies, curtains, pelmets, cornice boards and valances can be looked upon as the finishing accessory that pulls the look of a space together- much the way a pair of earrings or a singular gold cuff bracelet sets a fashion ensemble into style.
Draperies and curtains ( you say tomato, I say tomahto applies here) cover much more than windows- they make an open and shut case for adding pattern, texture, height, balance, and color to the space. Pelmets, cornice boards and valances complement draperies and curtains while providing a stylish alternative for covering and concealing the sins of install mistakes, measurement mishaps and drapery hardware.
Wood (i.e. plywood) is usually the material of choice for the construction of cornice boards. Cornice board shapes and styles range from box to scalloped which can be painted or covered with drapery fabric or upholstery.
Dave the Builder and I saved our newlywed nickles and dimes up for custom drapes. When we listed our house for sale I reserved the drapes. Those lined little darlings were coming with us regardless of any measurement restrictions! The window measurements of the space in the new house didn’t overly concern me. Plan B was in the woodworks. Dave the Builder built scalloped cornice boards using ½” plywood. He covered the forms with batting, measured and cut the fabric, and stretched and stapled it in place.
While the glue gun heated up I measured and cut the finishing trim. Decorative upholstery trim is my go-to solution for beautifully embellishing and beautifully hiding a defective seam or less than perfect corner fold.
For the DIY project minded, DIY Network has an excellent step by step guide to making a basic wooden cornice board here. This is a smart option, the BCL Drapery Hardware Marion Custom Moulding Curtain Rod Cornice comes complete with decorative cornice and built-in curtain rod.
Valances and cornices share the common trait of purpose and position. Intended as a decorative option for concealing drapery hardware, a valance is made of fabric that runs the top length of the curtain or drape. Popular styles range from the casual loose and free flowing treatment, traditionally tailored, the structured balloon, ruffled, or scalloped design, pinch pleated, tied and tasseled, or a simple straight finished piece shirred on the rod.
