Abstract: A bracket removably attaches to the front wall of a U-shaped headrail of a horizontal blind assembly for supporting an elongate decorative valance in covering relation to the front wall in order to conceal the headrail from view. The bracket includes a vertically extending main body having a front face and a rear face. Upper and lower prong members project outwardly from the top and bottom ends of the main body, respectively, and are structured and disposed for accommodating a range of valance heights in grasped, captivated receipt between distal ends of the prongs and the front face of the main body. An integral arm member extends downwardly from the top end of the main body, in spaced relation to the rear face for removably clipping the bracket to the front wall of the headrail at select positions, including a raised position when the headrail is “outside” mounted and a lowered position when the headrail is “inside” mounted.
