Long curtains (Floors G77)

I'm looking for long curtains please for my daughter's newly rented flat which is in an old building with high ceilings. All of the windows are much taller than any curtains I have (approx drop of 90 - 100inches). We would be very grateful for anything at all just to get the windows covered, if anyone is looking to pass any on. Thank you. And many thanks again for ones received which perfectly cover the huge bay windows
