Heavy cotton curtain fabric, unused, at least 6 metres long (Gerrards Cross SL9)

If anyone has a length, at least six metres, of heavy cotton curtain fabric, perhaps purchased long ago, but the curtains were never made, I can make good use of it. Thanks for looking. I can collect at a mutually agreeable time from Beaconsfield, Amersham, Chalfonts, Chesham and Gerrards Cross areas.
