A window, decorated with a valance, creates a festive, complete and holistic image of a decorative covering. Valance is a decoration in the form of drapery, which is placed in front of curtains, along the entire length of curtain rods. Apart from their decorative properties, valances can hide curtain rods or level out the window proportions, making it visually wider or narrower. The flowing lines of a valance can soften the straight contours of a window.
