A top stich in netting produced in France (6)
I believe the answer is:
alsace
'in france' is the definition.
('Alsace' is part of 'france')
'a top stich in netting' is the wordplay.
'top' indicates taking the first letters.
'in' becomes 'lace' (I can't justify this - if you can you should give a lot more credence to this answer).
'netting' is an insertion indicator (net can mean to contain or capture).
The initial letter of 'stich' is 's'.
's' inserted inside 'lace' is 'lsace'.
'a'+'lsace'='ALSACE'
'produced' acts as a link.
Can you help me to learn more?
(Other definitions for alsace that I've seen before include "French region bordering Germany and Switzerland" , "Region of France famous for white wine" , "area of France" , "somewhere in France" , "Region of France bordering Germany and Switzerland" .)
