Sewer's product in mesh damaged small person (9)
I believe the answer is:
hemstitch
'sewer's product' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'mesh damaged small person' is the wordplay.
'damaged' indicates anagramming the letters.
'small person' becomes 'titch' (titch can informally mean a short person).
'mesh' with letters rearranged gives 'hems'.
'hems'+'titch'='HEMSTITCH'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for hemstitch that I've seen before include "cough and pain" , "needlework" , "border" .)
