i have a large arch window in guest bedroom which takes up most of the wall (approx 8 feet high and 8 feet wide. Top is clear glass arch (with view), bottom is slider window. Awesome view but when have to get some privacy cover on window for evenings. Do not want to change arch view effect and trying to keep cost minimum and do as much as possible myself. No furniture in room yet, attached picture reflects room prior to purchase. Any ideas??
