How to put it together
- 1
Put on the lime green t-shirt or hoodie and the matching lime green leggings.
- 2
Cut out a large white circle, a medium blue circle, and a small black circle from the felt sheets to assemble the giant eye.
- 3
Glue the felt eye pieces together, then attach the completed eye to the center of your green shirt using fabric glue or safety pins.
- 4
Cut a wide, smiling mouth with pointed white teeth from black and white felt, and attach it just below the eye.
- 5
Place the blue Monsters University baseball cap on your head, ensuring the logo is centered.
- 6
Secure the small horn headband behind the cap, or pin the DIY horns directly onto the sides of the cap.
Makeup & hair
Keep makeup simple with a touch of green face paint around the eyes if desired, or leave it natural. Keep hair tucked neatly under the baseball cap so the focus remains on the hat and horns.
