We are redoing a 1950's mid-century modern home and our new master bedroom has a walnut sloped ceiling that extends to the outside. There is one wall of hexagonal windows so we are struggling to find alternatives for black out shades that would not obstruct the windows. We are on the ocean and face East so we know we will need shades. Ideally we would imbed them in the ceiling but with the slope and height a roll up shade would be very think. Any suggestions?
