I have a crescent shaped window, that does not open. It's above a standard window, and the only way to cover it is to purchase custom made cellulars in a fan shape. I've tried hanging a curtain all he way down, however it looks like a "stage". I've tried folding poster board into a fan shape, however it will not hold into the shape and looks tacky.
Are there any creative ways to addressing this window( i have 5 throughout the house) without incurring an enormous cost?
