Artist's support (5)
I believe the answer is:
easel
'artist's support' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for easel that I've seen before include "Artist's support frame" , "Blackboard supporter" , "Frame for a canvas" , "Support for 12's [ARTIST]" , "Wooden frame for an artist" .)
