Story's thread (4)
I believe the answer is:
yarn
I believe this is a double definition.
'story's' is the first definition.
(synonyms)
'thread' is the second definition.
(I know that thread can be written as yarn)
(Other definitions for yarn that I've seen before include "Long involved story" , "that'll keep you in stitches?" , "Rambling tale" , "Spun thread or wool or tall tale" , "Exaggerated story or spun thread" .)
