Abstract A window curtain comprising a textile fabric panel which, for the most part, is of single layer thickness. The panel is formed of a sheer translucent fabric. The panel has a plurality of vertical fabric edges, such as side edges and possibly edges of margins overlapped to form a seam or seams between separate pieces joined to form the panel. A pocket is fixed to the panel near the lower end of each vertical fabric edge, and nowhere else. Each pocket has an opening through which a weight can be inserted into, and removed from, the pocket. The panel has a bottom hem, and the pocket is located no higher than the upper edge of the bottom hem.
