A slatted blind is configured such that the slats close create a light blocking blind. The slats may be supported by a tilt cord that comprises a low stretch strand or a low stretch cord may be attached to the tilt cord. The slats may be connected to the supporting tilt cord such that when the slat is rotated to a closed position the slat is suspended from the rung. The rung may have an effective diameter of less than approximately 14 mil. Recesses may be formed in the slat for receiving the rung when the slat is in a closed position. A bottom rail may have a thickness approximately equal to the thickness of the slats. A protrusion may be formed on the back of the slats such that the rung pushes on the protrusion to force the slat against an adjacent slat when the blind is closed.
