Have requirement for lace borders — and sewing implement (6)
I believe the answer is:
needle
'sewing implement' is the definition.
(I've seen this before)
'have requirement for lace borders aeur' is the wordplay.
I cannot really understand how this works, but
'have' could be 'need' (synonyms) and 'need' is found within the answer.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for needle that I've seen before include "Movable bar in a compass" , "Irritate; pine leaf" , "Unnecessary" , "Annoy, tantalise" , "sledge?" .)
