If you are having a problem with what kind of window treatment to put on your angled windows you should take a look at what this customer has done. On the top layer of windows they have installed angled shutters on the 2 outside angled windows and then in the middle window which is a rectangle window they put a shutter to match the fan configuration of the side windows. In the window above the sliding glass doors and the windows on the sides of the slider they put a 2" wood blind with the same color as the shutters. In the sliding glass door they put 2 matching wood vertical. Nice nice nice!
