Abstract: A roll-up shade is doubled and its ends suspended from a head rail that is mounted above a window. One end is attached to a roller tube and the other end is attached to a stationary tube, with a bight being formed between the tubes. A first sheet is defined from the bight to the roller tube and a second sheet is defined from the bight to the stationary tube. A weighty rod is positioned in the bight to cause the bight to sag away from the head rail, and a shade guide surrounds the rod to guide the shade. With this structure, the roller tube can be rotated to pull up the first sheet and raise the bight or to lower the first sheet with bight, with the second sheet (i.e., the sheet that is directly attached to the stationary tube) remaining unmoving above the bight. The shade is patterned such that when the shade is raised and lowered, the relative motion between the two sheets causes the shade to alternatingly assume high and low opacity configurations. The roller tube can be motorized if desired.
