Seaside yarn (6)

I believe the answer is:

strand

This clue is a double definition.

'seaside' is the first definition.
(thesaurus)

'yarn' is the second definition.
(thesaurus)

(Other definitions for strand that I've seen before include "Beach or single hair" , "Ply" , "Scottish gutter" , "Beach - desert" , "Yarn - thread" .)

I've seen this clue in The Globe and Mail.
