It resembles a snake (a cobra) made entirely out of fabric, wears a half-mutilated doll face to cover half of its face, and has a pair of three metallic insect-like limbs with two pairs of insect-like hands; four of them have robotic hands, one has a seam-cutting blade, two others have sewing needles, and the remaining arm has a pair of old scissors. Seamstress somewhat resembles a mythical creature Lamia (a half-human and a half-serpent).
Abilities and powers
The Seamstress uses neuro-shock hypnosis to induce her victims with quick bursts of blinding blue and white light from the eyes of 2's desceased corpse, which is sewn to her tail, before binding the self-induced target with red thread. The Seamstress then stows her bound victims inside her belly, which can open and close at will.
One of the most predominant features of the Seamstress is the snake machine's constant hissing, which indicates the nearness of the Seamstress. The machine can change the looks of its hood by spreading metal arms attached to the fabric, either folding it up over her face or spreading it out like a fan. The length of the Seamstress is 1 meter, and the height of standing position would be about 6 inches. The Seamstress's distinct rattling hiss indicates the nearness of the mechanical snake.
In the film, the Seamstress captured 7 and 8 using the corpse of 2, causing 9 and the other remaining Stitchpunks to chase the fabricated beast to the factory. 9 goes into the factory and rescues 7, but 8 has his soul removed by the Fabrication Machine. 9 used a fake dummy to attach it to the Seamstress's body and hoisted the Seamstress to two rotating gears, thus crushing and killing the reptilian menace.
- The design of the Seamstress in the film was a nod towards The Beldam from the film Coraline, which was also made by Focus Pictures.
