Cover pain from application of needle (7,6)

I believe the answer is:

blanket stitch

I'm a little stuck... Click here to teach me more about this clue!

'application of needle' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'cover pain' is the wordplay.
'cover' becomes 'blanket' (blanket is a kind of cover).
'pain' becomes 'stitch' (pain in the body).
'blanket'+'stitch'='BLANKET-STITCH'

'from' is the link.

Can you help me to learn more?

(Another definition for blanket stitch that I've seen is " Way of edging thicker materials".)

I've seen this clue in The Daily Express.
