Make lace (3)
I believe the answer is:
tat
'make lace' is the definition.
(to tat is make lace from thread)
This is the entire clue.
(Other definitions for tat that I've seen before include "Tawdry and shabby article" , "Make knotted lace" , "Shoddy stuff (colloq.)" , "Make lace using a small shuttle" , "Worthless goods" .)
