<p>An architectural covering, such as a roller shade (1), including a vertically - extending layer (27, 29, 627) of a shade material (5) between an elongate longitudinally - extending roller (3) and an elongate longitudinally - extending bar (7); an elongated groove (15, 17) extending longitudinally along the length of the outer surface (3A) of the roller (3); a top portion (39, 673) of the layer (27, 29, 627) of shade material (5) being attached to an elongate longitudinally-extending top attachment member (23, 25) in the groove (15, 17); the layer (27, 29, 627) of shade material extending longitudinally along the roller (3), so that partial rotation of the roller causes the layer to move vertically and continued rotation of the roller winds the layer around the roller, characterized in that: the outer surface of the top attachment member (23, 25, 123, 223, 323, 423, 523) has at least two peaks (83, 183, 283, 383, 483, 583) along its length such that when the upper portion (39, 673) of the layer (27, 29, 627) of shade material (5) is attached to the attachment member, the peaks extend through the upper portion of the layer, preferably through an open structured section (71) of the top portion of the layer. <IMAGE></p> |
