Artists' stands (6)
I believe the answer is:
easels
'artists' stands' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for easels that I've seen before include "Supports for paintings" , "Leases them out to artists" , "Leases (anag)" , "Stands for artists' canvases" , "Painters' stands" .)
