Drawing stick (6)
I believe the answer is:
crayon
'drawing stick' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for crayon that I've seen before include "Coloured wax pencil" , "Producer of sketch" , "alternative to charcoal" , "Pencil of chalk or wax" , "(Draw with) a coloured stick" .)
