What’s used for a light fabric (10)

I believe the answer is:

candlewick

I believe this is a double definition.

'what's used for a light' is the first definition.

'fabric' is the second definition.
(type of embroidery)

(Other definitions for candlewick that I've seen before include "Soft cotton tufted material" , "Bedspread material" .)

I've seen this clue in The Times.
