How to put it together

1
Select your character theme and choose a matching solid-colored hoodie and pants.
2
Sketch your design elements, such as animal ears, dinosaur spikes, or wings, onto stiff felt sheets.
3
Cut out the felt shapes carefully using sharp fabric scissors.

Arrange the felt pieces on the hood, back, or chest of the hoodie to test the placement.

Secure the felt pieces to the fabric using double-sided fabric tape, hot glue, or safety pins.
6
Put on the matching pants and pull the decorated hood over your head to complete the look.

Makeup & hair

Keep hair flat or tied back so the hood fits comfortably over your head. Apply simple face paint, like a black nose and whiskers for an animal look, to complement your hoodie theme.

couples: Create a matching pair like a red hoodie for a devil and a white hoodie for an angel.

Tips

Use safety pins instead of glue if you want to reuse the hoodie for everyday wear after Halloween.
If trick-or-treating in cold weather, size up your hoodie so you can layer warm clothes underneath.
Use stiff felt rather than soft felt so that ears or spikes stand upright on the hood instead of flopping over.
