Lots of blades involved in making this cloth (4)
I believe the answer is:
lawn
This clue is a double definition.
'lots of blades involved in making this' is the first definition.
(as in blades of grass)
'cloth' is the second definition.
(lawn is a type of fabric)
(Other definitions for lawn that I've seen before include "Grassed area" , "Garden feature" , "Cultivated and mown grass" , "Cultivated and mowed grass" , "Area of mown grass" .)
