I will go to Home Depot and ask for clothes line, but, before I do, do
you have experience with something like this that you can make
recommendations?

How do you plan to hang anything on a line 50 feet up? I'm thinking you
may need 200 feet of line, so you can pull the clothes to the window.
They did this a lot in tenement apartments.

In any event, clothesline is made of cotton and will fail with exposure
to weather. Probably a better choice is Dacron line with UV protection.
I would guess HD wouldn't carry this, as it is a product suited for
marine use. Nylon is another option, but it is very stretchy.
