Form of needlework one may get hooked on? (7)

I believe the answer is:
crochet
'form of needlework' is the definition.
'crochet' can be an answer for 'needlework' (crochet is a kind of needlework). I am unsure of the 'form of' bit.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for crochet that I've seen before include "piece of handiwork" , "Type of needlework" , "working with hook and loops" , "Decorative work using loops" , "In music, a note equal to half a minim" .)
