Already made a perfect braid design (13)
I believe the answer is:
prefabricated
'already made' is the definition.
'prefabricated' can be an answer for 'made' (thesaurus). I am not certain of the 'already' bit.
'a perfect braid design' is the wordplay.
'design' indicates anagramming the letters.
'a'+'perfect'+'braid'='aperfectbraid'
'aperfectbraid' is an anagram of 'PREFABRICATED'.
Can you help me to learn more?
(Other definitions for prefabricated that I've seen before include "ready to be joined together" , "Easily erected on a building site" , "Ready to be assembled on site" , "Made for easy assembly" , "Manufactured so as to allow easy assembly on site" .)
