A stand for new art (5)
I believe the answer is:
easel
'a stand' is the definition.
(stand for an artist's canvas)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for easel that I've seen before include "Artist's wooden frame" , "board support" , "Supporter for the artist" , "Lease (anag)" , "Three-legged supporting frame" .)
