Bark threads woven into fabric (4)
I believe the answer is:
woof
'bark' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for woof that I've seen before include "Something woven" , "Cry of dog - texture of fabric" , "Sound of dog's bark" , "As dog goes" , "boxer's outburst" .)
