Hi! i have a floor to ceiling wall window in my bedroom with a curtain rod drilled to the ceiling as close as possible to the window with black out fabric sewn on the back of the curtain. I live on a street that has street lights on all night, as I'm very light sensitive and the curtain still lets light seep out of the sides. Problem is, the construction of the window doesn't allow close drilling since there is an internal metal frame. Any ideas?
We actually suffer from the same light leakage, but with roller shades, so we're interested in readers' experiences and ideas about this matter. Here are some similar topic threads with a lot of good information related to blocking out light:
