Figures to make nets (4)
I believe the answer is:
tens
'figures' is the definition.
(ten is a number)
'make nets' is the wordplay.
'make' is an anagram indicator.
'nets' anagrammed gives 'TENS'.
'to' acts as a link.
(Other definitions for tens that I've seen before include "At least 20" , "X, X, X, ..." , "Cardinal numbers" , "Half-scores" .)
