Set to spin a bit of a yarn (5)

Ross

I believe the answer is:

telly

'set' is the definition.
(telly is a kind of set)

'spin a bit of a yarn' is the wordplay.
'spin' becomes 'tell' ('tell' can be a synonym of 'spin').
'a bit of' indicates taking the first letters.
The first letter of 'yarn' is 'y'.
'tell'+'y'='TELLY'

'to' is the link.

(Other definitions for telly that I've seen before include "cop in seventies" , "'The box' (colloquial)" , "- - Savalas" , "Television" , "Familiar name for TV" .)

I've seen this clue in the Evening Standard.
