Layers of linen (6)
I believe the answer is:
sheets
This clue is a double definition.
'layers' is the first definition.
(I've seen this in another clue)
'linen' is the second definition.
(I've seen this before)
'of' is the link.
(Other definitions for sheets that I've seen before include "Pieces of paper or bedclothes" , "Bed covers" , "She set them on the bed" , "Bed coverings for the sailor's ropes" , "Pieces of paper and bed linen" .)
