Hello from Eddie in Pittsburgh. Question: Does anyone sell something like dark sheets of plastic that you can apply to windows for darkening the light in a room? My neighbor has the apartment's floodlight just below her window and even with blinds a fair amount of light leaks into the bedroom. I was picturing sheets that could be cut and placed on the glass (not glue, but made from the kind of material of used in temporary window decals..peels off). It would be a dark material to cut down on the stray light. (If not, can anyone recommend a slingshot?/JUST KIDDING...) Thank you very much..
