I'm in need of some ideas on how to decorate four large windows in the living room of a mobile home. Each window measures 48" in width by 54" in height. If you look closely at the attached picture you will see that each window is separated slightly by 3" of wall.

The view from these windows is that of a lake. The trailer is located on lake lot. So it is important that view is not obstructed.

I would like to do some type of valance or cornice but not sure if each window should be treated separately, or group in sets of two, or group as one massive window.

To minimize the black metal window frame I would like to hang panels which will cover black metal window frame and the 3" wall space.

Any suggestions would be greatly appreciated.
