Sheer material in newspaper attracting unknown journalists essentially (7)
I believe the answer is:
organza
'sheer material' is the definition.
'newspaper attracting unknown journalists essentially' is the wordplay.
'newspaper' becomes 'organ' (I've seen this before**).
'attracting' is a charade indicator (letters next to each other).
'unknown' becomes 'z' (algebra).
'essentially' says to take the centre.
The central letter of 'journalists' is 'a'.
'organ'+'z'+'a'='ORGANZA'
'in' is the link.
(Other definitions for organza that I've seen before include "Transparent silky material" , "dress material" , "Transparent silk material" , "Silky cloth" , "Thin material" .)
