Flip-chart holders (6)
I believe the answer is:
easels
'flip-chart holders' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for easels that I've seen before include "Supports for paintings" , "Stands for blackboards, artists' paintings etc" , "Artists' tripods" , "Painters' stands" , "Leases (anag)" .)
