Bed linen (6)
I believe the answer is:
sheets
'bed linen' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sheets that I've seen before include "They get blanket coverage" , "Pieces of paper or bedclothes" , "She set them on the bed" , "Bedclothes, sailing ropes and paper" , "Sail-ropes and bedclothes" .)
