Nice curtains. For my 8’ sliding glass door, two panels were not enough. I bought two more  panels for a total of four panels. By stitching two panels together, with my faithful old Singer Sewing machine, I made two double wide panels. The look works well.  We love the max black-out feature. (Light escapes from above   below the panels.) However, light does not penetrate the panels.  
After almost 20 years of “temporary” window treatments, I’m grateful to have found these drapes. We are happy with the result.  PS Our 10 year old Yorkie-Chi, Rambo, photo-bombed one pic.  I didn’t think you’d mind.
