I would like to put some plastic sheets on the windows of my apartment, preferably on the inside since I live on a high rise and can't reach the exterior. I've seen these plastic sheets that you can put on that partially block (or make hazy) how much you can see inside (especially at night when things are dark outside and the lights on on inside). What are they called and does anyone know where I can get them (preferably online)? Thanks!
I do the same thing but with Saran wrap. Using rolls of tape to seal it completely. Works great.
