A slatted blind (10) includes a headrail (12) with a pair of ladder cords (16, 18) depending therefrom with slats (14) supported on the wefts (44, 52) extending between the warps (42a,b, 50a,b) of each cord and further includes a tilt mechanism (20) to extend one warp of each cord and to retract the other in order to tilt the slats. The preferred tilt mechanism (20) includes a pair of slides (60, 62) positioned on the bottom wall (26) of the headrail (12). The ends of the warps (42a,b, 50a,b) are coupled with the slides (60, 62) on opposed sides of respective cord holes (82, 90) defined through the slides (60, 62) and extend therethrough and also through respective cord openings (30, 32) in the bottom wall. Back and forth shifting of the slides (60, 62) along the bottom wall (26) alternately extend one warp of each cord and retract the other in order to tilt the slats.
