Perhaps hide artwork using rag as well (6)
I believe the answer is:
tattoo
'perhaps hide artwork' is the definition.
(as 'hide' can mean 'skin')
'rag as well' is the wordplay.
'rag' becomes 'tat'.
'as well' becomes 'too' ('too' can be a synonym of 'as well').
'tat'+'too'='TATTOO'
'using' acts as a link.
(Other definitions for tattoo that I've seen before include "Needlework! - performed by soldiers!" , "Personal design" , "display involving military band" , "Military display - needlework!" , "Display in Edinburgh" .)
