I’ve had these Curtains for a number of years and they’ve been in storage for the last 10 maybe.
They are cotton
Each curtain measures 92 inches long by 72 inches wide measurement taken across the bottom.
The pattern match at the centre isn’t accurate although the line across the curtain pattern is fine if you are not overly fussy about this as it doesn’t really notice to me when they’re up but I need to mention it. See the pictures.
They’ve got a good 3 inch header tape.
The linings are good though little discoloured near the bottom.
Not sure of their age maybe 30 - 40 years I’m thinking they are from the 80s

They are weighted at the hem.
Apart from a little bit of fading to the leading edges, the fabric is in very good condition.
Maybe approximately 8 yards of fabric here. 
Please don’t hesitate to ask if you have any questions.
Thank you
