Blocking the windows inconspicuously

How can you block windows without making a place look like a grow house or a meth lab? Blinds is obvious, but that doesn't block the amber light.

Is there some cool trick to this?

If you really want to make it look cool....make window-sized posters that look like a room Also hang a flag outside of your house and in 1 window. When that's done put mylar behind it.
I'm sure you'll get a lot of ideas.

Hang a thick sheet or bed comforter behind the blinds so all you see is blinds from the outside

all kinds of duct tape and cardboard.

take the blinds and hang them inside the window frame then duck tape and cardboard the outside of the window frame so it looks like blinds but its really a ghetto ass meth lab

I hung a comforter and nobody asks questions after 8 months

Same with me hung a sheet on outside of blinds so from outside looks like i got the blinds closed
