- Arthur Weasley: "I don't know whether you know what — what stitches are?"
- Molly Weasley: "It sounds as though you've been trying to sew your skin back together, but even you, Arthur, wouldn't be that stupid."
- — Arthur and Molly Weasley in St. Mungo's[src]
- When Arthur Weasley was brought to St. Mungo's Hospital for Magical Maladies and Injuries after he was attacked by Nagini in 1995, Augustus Pye, a trainee Healer, suggested trying stitches to heal Arthur's wounds. This attempt ended up fruitless, as Nagini's fangs had a poison in them that dissolved the thread. 
- A boy named Robbie Fenwick once bit Mr. Granger. Mr. Granger had to be sewed with ten stitches.
