Still looking young, suitable for artist’s sketching? (7)
I believe the answer is:
unlined
'still' is the definition.
Both the definition and answer are adjectives. Perhaps you can see a link between them that I can't see?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for unlined that I've seen before include "Blank paper could be thus" , "Like plain writing paper" , "Having no inner layer" , "Wrinkle-free" , "Like some notepaper" .)
