Make double (in sheep farming?) (4)
I believe the answer is:
fold
'make double' is the definition.
'fold' can be an answer for 'double' (thesaurus). I am unsure of the 'make' bit.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for fold that I've seen before include "Church following" , "stop functioning" , "Bend over; pen" , "Tuck - pen" , "Prepare pages to put in small envelope" .)
