Please leave, carrying a stand (5)
I believe the answer is:
easel
'a stand' is the definition.
(stand for an artist's canvas)
'please leave carrying' is the wordplay.
'carrying' indicates a hidden word.
'EASEL' is hidden in the letters of 'please leave'.
(Other definitions for easel that I've seen before include "Artist's wooden frame" , "Support in the studio" , "Painting support" , "Artist's stand for painting" , "Artist's canvas holder" .)
