I suppose that's one way to do it...

My brother runs a car parts retail shop (three of them, in fact). I jokingly noted once that he should put curtains up on the backroom window to keep the light out.

Well, he did...kinda.

Haha, very inventive and a good use of space

Haha, I would do that, I have about 3 houses 1 of which was inherited from my parent's as they passed away, so space is an issue for me.
