Some people like to use two or three A curtain (sometimes known as a drape, mainly in the United States) To hang a scarf valance you must first have a curtain rod that matches the decor of the room. Description from I searched for this on
Icicle lights strung vertically behind window sheers - best Xmas decorating idea ever!! Got the idea from pinterest, but think my version turned out better than the inspiration pic (biased ;-)). Used command hooks as well as the curtain hardware to hang the lights; 2 stings per window - don't want to be stingy with the light. I also spent time hooking the "icicles" together horizontally, from the vertically strung wire, to give a more fully lit effect. Ambiance abound!
