How to put it together

1
Lay the hooded sweatshirt flat on a table with the hood pulled up and the back facing you.
2
Cut several pairs of matching triangles from your contrasting felt sheets to make the spikes.
3
Glue or sew the pairs of felt triangles together to make them stiff, leaving the bottom edges unglued so they can flare out.
4
Attach the spikes in a straight line starting from the top of the hood, running down the center of the back to the hem.
5
Secure the plush tail to the back waistband of the sweatpants using safety pins or fabric adhesive.
6
Slide the clawed shoe covers over your child's sneakers and put on the completed hooded sweatsuit.

Makeup & hair

Since the hood covers most of the head, hair can be kept simple and tucked away. For a fun touch, use face paint to draw green scales on their cheeks or a small dinosaur silhouette near their eye.

Tips

Prioritize comfort by choosing soft, breathable cotton hoodies so your child doesn't overheat while trick-or-treating.
If trick-or-treating in cold weather, size up the hoodie so you can easily layer warm clothes underneath.
Add reflective tape to the back of the tail or the sides of the hood to ensure high visibility at night.
Keep the tail detachable with Velcro or safety pins so your child can sit comfortably in a car seat or stroller.
