How to put it together
- 1
Put on the brown sweatpants and zip-up hoodie as your base layer.
- 2
Paint black bands in the middle of the white paper straws using acrylic paint or a marker, leaving the tips white to look like authentic quills.
- 3
Cut a semi-circle out of the foam board to act as the quill harness.
- 4
Hot glue the painted straws in a fan-style radiating pattern onto the foam board.
- 5
Attach the quill harness to the back of the hoodie using heavy-duty safety pins or fabric glue.
- 6
Cut simple teardrop shapes from the brown and pink felt to make ears, then glue them to the sides of the hood.
- 7
Add a small black felt circle to the tip of the hood to represent the nose.
Makeup & hair
Keep hair simple or tucked into the hood. Use brown and black face paint to draw a small round nose on the tip of your nose and add a few cute whiskers on your cheeks.
