How a Swede possibly did needlework (5)
I believe the answer is:
sewed
'did needlework' is the definition.
(I've seen this before)
'how a swede' is the wordplay.
'how' is an anagram indicator (I've seen this in other clues).
'swede' with letters rearranged gives 'SEWED'.
'possibly' is the link.
(Other definitions for sewed that I've seen before include "Joined" , "Used needle and thread" , "Stitched" , "Fastened with thread" , "Did needlework" .)
