As an artist I must get involved with paper and leather (3-10)
I believe the answer is:
pre-raphaelite
'as an artist' is the definition.
'i must get involved with paper and leather' is the wordplay.
'must get involved with' is an anagram indicator.
'and' says to put letters next to each other.
'paper' after 'leather' is 'leatherpaper'.
'i' anagrammed with 'leatherpaper' makes 'PRE-RAPHAELITE'.
(Other definitions for pre-raphaelite that I've seen before include "Violent criminality" , "English artist such as Holman Hunt or Dante Gabriel Rossetti" , "eg Holman Hunt" , "Victorian artist such as Millais" , "Eg, Millais or Rossetti" .)
