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

'link' is the definition.
(I've seen this before)

I can't explain the remainder of the clue.

(Other definitions for knit that I've seen before include "Unite together" , "Tighten (eyebrows) in a frown; unite" , "Unite closely" , "manufacture clothing?" , "Make a scarf, say" .)

I've seen this clue in the Sydney Morning Herald.
