Layers of bedclothes (6)
I believe the answer is:
sheets
I believe this clue is a double definition.
'layers' is the first definition.
(I've seen this in another clue)
'bedclothes' is the second definition.
(I know this)
'of' is the link.
(Other definitions for sheets that I've seen before include "Leaves" , "They get blanket coverage" , "Bed coverings for the sailor's ropes" , "Flat pieces, of cloth or paper say" , "Pieces of paper or bedclothes" .)
