I'm sure something you just stick on works for some. Here, it would fall
off the next day. Or I'd break the glass when fitting it. ;-)

I did the hall side window and stair top window with some patterned
frosted film, because they were over looked. I did them 12 months ago,
with some film from China and they are fine.

Idea was to avoid having to draw curtains all the time.
