Curtains approx to fit a window 75"x 60"width (AB23)

I went searching the charity shops in Aberdeen only to find my favourite one, the Salvation Army has closed, and no charity shop appears to stock curtains any longer. Apparently they don't sell well. I only have the approximate measurements of the window as it is in our youngest son’s flat. I think a 75 inch drop approximately 190cms for a window width of approximately 60 inches or 155 cms. Happy Freegling all! Mary
