Ordered the 58" x 72" shade but the header is 57 1/2" and the actual shade was only 55" wide.  Left big gaps on the side of the shade and looked terrible when installed.  Other brands of this type of shade fit perfectly in the sizes we ordered.  It also isn't as substantially designed as shades made by other manufacturers.  Very disappointed after paying $144 for a shade that doesn't fit, so it was returned.  Unfortunately, we also had to pay return shipping -- irritated at Wayfair's return policy when the item was returned because it is not as described.  Two stars for being easy to put up.
