Wind the thread (5)
I believe the answer is:
twine
I believe this is a double definition.
'wind' is the first definition.
(to twine is to curl or wind around)
'the thread' is the second definition.
(I've seen this in another clue)
(Other definitions for twine that I've seen before include "Stout string" , "Garden string" , "String of twisted fibres" , "Knot" , "can get into knots" .)
