摘要： A covering for an architectural covering is provided. The covering may include a rotatable outer roller, a rotatable inner roller, a first shade secured to the outer roller, and a second shade secured to the inner roller. The outer roller may define an elongated slot extending along a length of the outer roller and opening to an interior of the outer roller. The inner roller may be received within the outer roller and may define a central longitudinal axis. The first shade may be retractable onto and extendable from the outer roller. The second shade may extend through the elongated slot and may be retractable onto and extendable from the inner roller. The elongated slot may be substantially horizontally aligned with the central longitudinal axis of the inner roller when the first shade is in a fully extended position.
