"They're hats for house-elves. I did them over the summer. I'm a really slow knitter without magic but now I'm back at school I should be able to make lots more."
—Hermione Granger's use of the knitting charm[src]

The Knitting charm (incantation unknown) is used to charm knitting needles to perform their task autonomously.


Hermione Granger used this charm while she was at Hogwarts to knit the clothes she was leaving out for the house-elves.

Molly Weasley used this charm on knitting needles at the Burrow to knit clothing (presumably the Christmas presents) whilst she was absent.
