It was interesting installing these. I keep thinking in terms of wood-frame structures, but when I was drilling the holes for mounting the curtains, the drill suddenly hit “something hard” and “gray powder” started coming out. Duh! The outside walls are all cinderblock! Not sure how I forgot that, but it sure made the whole thing a bit different.
Had to wear a dust mask to keep from breathing too much powdered silicon. Had to use a concrete drill bit. Takes more time and patience to drill into it as well, of course.
Anyway, adventures in getting up the curtains are done for the living room, bedroom, and dining room. The kitchen has flowery plastic on its window. All that remains is the TV room, and I’ve got ideas for that (it needs to be darker in there).
