We have the older style shutters (1 inch?) downstairs and need something in the three dormer windows. The one in the center is above a two-story foyer and not accessible without a ladder. Right now it has no window treatment. The two on each side are bedrooms and have roller shades as a temporary measure. I'd like all three to look the same from the outside (although I realize that right now the shutters downstairs are not consistent!).

Advice?
