Use a needle like this, say (3)
I believe the answer is:
sew
'use a needle' is the definition.
(you use a needle when sewing)
'like this say' is the wordplay.
'like this' becomes 'so' ('like so').
'say' shows a homophone (sound like).
'so' sounds like 'SEW'.
(Other definitions for sew that I've seen before include "Make stitches" , "Fasten with stitches" , "Do some needlework" , "Stitch with needle and thread" , "Use a needle and thread" .)
