Doily material (4)
I believe the answer is:
lace
'doily material' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lace that I've seen before include "Delicate material" , "Shoe string" , "Famous play ''Arsenic and Old . . . .''" , "Fine open fabric" , "Tear" .)
