What it takes to make a sewer work well? (11)
I believe the answer is:
needlecraft
'what it takes to' is the definition.
I can't tell whether this definition defines the answer.
'a sewer work well?' is the wordplay.
'a sewer' becomes 'needle' (I've seen this before).
'work well?' becomes 'craft' (I can't explain this - if you can you should believe this answer much more).
'needle'+'craft'='NEEDLECRAFT'
'make' is the link.
Can you help me to learn more?
(Other definitions for needlecraft that I've seen before include "Sewing, embroidery" , "Art of stitching" , "Skill in fixing sails, say" , "Talent shown by Little Dorrit" , "Art of sewing" .)
