Sewn (8)
I believe the answer is:
stitched
'sewn' is the definition.
(I know that sewn can be written as stitched)
This is all the clue.
(Other definitions for stitched that I've seen before include "Joined up" , "Fastened by sewing" , "with bits of cotton in?" , "Fastened with a needle and thread" , "after action in theatre?" .)
