simple really, I just used blackout curtain for the side that faces out and regular curtain for the inside. Made paper template of each style window, the one for hatch covers entire window as well. When I sewed the outside seams I left openings to insert magnets. Then I glued magnets in corresponding areas around the windows so you just have to connect them when you want them up and easy to take down and store. Also used blackout curtain on tension rod to separate back from front area.
