Please leave, taking a stand (5)
I believe the answer is:
easel
'a stand' is the definition.
(stand for an artist's canvas)
'please leave taking' is the wordplay.
'taking' indicates a hidden word (the answer is carried or taken by the clue).
'EASEL' is hidden in the letters of 'please leave'.
(Other definitions for easel that I've seen before include "Tripod for an artist" , "Artist's tripod" , "Blackboard-frame" , "Artist's support frame" , "Stand in a studio" .)
