Bedclothes used as ropes (6)
I believe the answer is:
sheets
This clue is a double definition.
'bedclothes' is the first definition.
(I know this)
'ropes' is the second definition.
(I've seen this before)
'used as' acts as a link.
(Other definitions for sheets that I've seen before include "Bedclothes, sailing ropes and paper" , "Flat pieces, of cloth or paper say" , "Bedclothes to be found on ships?" , "They get blanket coverage" , "Pieces of paper and bed linen" .)
