Covering for an architectural opening having nested rollers

A covering for an architectural opening, comprising:

• a rotatable outer roller;
• a rotatable inner roller received within the outer roller;
• a first shade coupled to and adapted to be wrapped around the outer roller, the first shade retractable onto and extendable from the outer roller;
• and
• a second shade coupled to and adapted to be wrapped around the inner roller, the second shade retractable onto and extendable from the inner roller and having side edges that are aligned with the ends of the inner roller;
• wherein:
• the side edges of the second shade are aligned with the ends of the outer roller;
• the outer roller includes a first shell and a second shell each having a first longitudinally- extending edge portion and a second longitudinally-extending edge portion;
• the second longitudinally-extending edge portions of the first and second shells are peripherally spaced apart from one another to define an elongated slot extending along a length of the outer roller between the ends of the outer roller and opening to an interior of the outer roller;
• and
• the second shade extends through the elongated slot.

A covering for an architectural opening, comprising:

• a rotatable outer roller including a first shell and a second shell and defining an elongated slot extending along a length of the outer roller and opening to an interior of the outer roller;
• a first bushing engaged with a first end of the outer roller;
• a second bushing engaged with a second end of the outer roller;
• a rotatable inner roller received within the outer roller and defining a central longitudinal axis;
• a first shade coupled to the outer roller, the first shade retractable onto and extendable from the outer roller;
• and
• a second shade coupled to the inner roller, the second shade extending through the elongated slot and retractable onto and extendable from the inner roller;
• wherein the elongated slot is substantially horizontally aligned with the central longitudinal axis of the inner roller when the first shade is in a fully extended position;
• and
• wherein the first and second bushings maintain a width of the elongated slot.
