The material about me is a gross fabrication (8)
I believe the answer is:
gossamer
'the material' is the definition.
(gossamer is a kind of material)
'me is a gross fabrication' is the wordplay.
'fabrication' indicates anagramming the letters.
'me'+'a'+'gross'='meagross'
'meagross' anagrammed gives 'GOSSAMER'.
'about' acts as a link.
(Other definitions for gossamer that I've seen before include "Filaments of a spider's web" , "Very finest textured silk" , "Fine spider-threads" , "Flimsy, delicate material" , "Some rags (anag.)" .)
