not something i’ve given much attention, the different sorts etc, history of, origins etc. In fact I had to look it up to check if curtains could be called blinds. That naive.
the idea seems straightforward enough, a (adjustable) screen, for windows. Of course there are decorative aspects and more too, often.
I guess my eyelids are blinds, of sorts. Seems obvious.
i’m wondering what the first protoblinds were, way back on the african savanna, and back further. Other primates, and perhaps other mammal relatives. Man’s best friend, the canine, do they have blinds, or express any behavior that suggests a feel for what a blind does.
avians too, i’m sure i’ve seen them put foliage between me and them
