Artistic support (5)
I believe the answer is:
easel
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">artistic support</span>' is the definition.<br/ ><span class="explanation-format__explanation">(an easel holds an artist's canvas up)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for easel that I've seen before include "Artist's tripod" , "board support" , "Support for artist's canvas" , "Wooden frame for an artist" , "Support in the studio" .)
