Vellum for instance (9)
I believe the answer is:
parchment
'vellum for instance' is the definition.
(I know that vellum is a type of parchment)
This is all the clue.
(Other definitions for parchment that I've seen before include "Writing sheet made from animal skin" , "goatskin?" , "quality paper" , "Old writing material" , "High-quality paper" .)
