Put on the black long-sleeve shirt and black pants or leggings as your base layer.
2
Stuff the three pairs of black knee-high socks with the fiberfill until they are firm but flexible.
3
Attach the open ends of the six stuffed legs to the black belt using safety pins or fabric glue, spacing them evenly with three on each side.
4
Fasten the belt securely around your waist so the extra legs drape down your sides.

Tie a piece of clear fishing line from the wrist of your shirt down through each of the three stuffed legs on that side, leaving enough slack for movement.

Put on the black beanie decorated with googly eyes to complete the spider's head.

Keep hair tucked neatly under the black beanie. For makeup, apply dark smokey eyeshadow and optionally draw a small black spiderweb on one cheek using black liquid eyeliner.
