Abstract: A window shade assembly includes a flexible shade material having a pair of non-beaded vertical edges positioned in a pair of opposed vertical side channels. A re-channeling system includes a lip to at least partially define a plane of the flexible shade material within the side channels, and a bottom rail irremovably and slidingly received in each side channel. The side channels can be two parts. A single resilient seal strip is used with the side channels to seal the flexible shade material. The seal strip can be an edge of the flexible wrapping material for the side channels.
