Abstract
A window covering includes a roller attached to a mounting device and an actuation device attached to the roller to rotate the roller in at least one of a first direction and a second direction. A front member is attached to the mounting device. A second member is attached to the roller. A plurality of ballast members are attached to at least one of the front member and the second member. Each ballast member is configured to cause or enable the front member to form substantially parallel folds when the second member is wound about the roller to retract the front member to a retracted position. Preferably, the folds are similar to or exactly like the transverse folds in shade material that are formed when a conventional Roman shade is raised.
