Make lace: stuff of poor quality (3)
I believe the answer is:
tat
I believe this clue is a double definition.
'make lace' is the first definition.
(to tat is make lace from thread)
'stuff of poor quality' is the second definition.
(Other definitions for tat that I've seen before include "Cheap clothes" , "Cheap rubbish" , "Tawdry things" , "Inferior articles" , "Shoddy stuff (colloq.)" .)
