Nagini, Voldemort’s constant companion and—as Harry eventually learns—a Horcrux, is first introduced in Harry Potter and the Goblet of Fire. Twenty feet long and covered in reflective scales, she protects her master and does his deadly bidding. The design for Nagini evolved through the films, with designers studying and filming real snakes to get this creature just right. Her final design for Harry Potter and the Deathly Hallows – Parts 1 and 2 combines a python and an anaconda, with cobra and viper elements in her face and movements.

Worked as a four-stitch i-cord for the desired length, this lariat-style necklace is a quick and straightforward accessory. The head of the snake is knit back and forth in two pieces and joined at the mouth, allowing the i-cord to pass through, wrap around the wearer’s neck, and be adjusted for fit. Beaded eyes are sewn on, and the muted metallic yarn creates sheen without being scratchy.

Lariat also needs six 5mm bi-cone beads.
