Reach instruction for knitting a giant sweater? (4,1,4,3)
I believe the answer is:
make a long arm
'giant sweater?' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'reach instruction for knitting a' is the wordplay.
I cannot quite understand how this works, but
'reach' could be 'make' (synonyms) and 'make' is found in the answer.
'a' is found in the answer.
The remaining letters 'longarm' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for make a long arm that I've seen is " Grab everything you can!".)
