Wondering what the best way to approach this project is. None of the jams are wide enough for the walls and in the picture of the larger windows the side windows have jams that are wider than the middle window. It is difficult to see in the picture but all the windows are around 3 to 4 inches apart. Should I build individual jam extension then treat them as one large window and trim them in that fashion or do them each individually? Or is there another way to go about it?
