Toothless Dragon Costume: DIY Guide

This guide shows you how to build a Toothless dragon costume from scratch—the beloved Night Fury from How to Train Your Dragon—using foam, fabric, and a few clever tricks. The finished costume is a wearable, head-to-tail outfit that works for Halloween, cosplay, or a themed party. You’ll need basic sewing and crafting skills, but no special equipment beyond a glue gun and scissors.

What You’ll Need

Black hoodie and black sweatpants (base layer)
Black felt or fleece fabric (2–3 yards / 2–3 m, depending on size)
Black craft foam sheets (12″ x 18″ / 30 x 45 cm, about 10 sheets)
Gray or silver fabric paint or acrylic paint
Red or yellow LED glow sticks or small battery-operated fairy lights
Black thread and needle or sewing machine
Hot glue gun and glue sticks
Scissors or rotary cutter
Measuring tape
Wire or pipe cleaners (for tail and wing structure)
Black headband or old baseball cap (for the head)
Cardboard or poster board (for pattern making)

Step-by-Step

Create the head piece. Take the black headband or cap. Cut two ear shapes from craft foam—they are rounded triangles, about 6 inches (15 cm) long. Hot glue them to the sides of the headband so they stick up. Cut two small horn shapes (curved cones) and glue them to the top of the headband. Paint the inner ear a lighter gray, if desired.
Make the eyes. Cut two oval shapes from yellow or green felt, about 2 inches (5 cm) wide. Glue them to the front of the headband, just below the ears. To make them glow, tape a small LED light (from a glow stick or fairy light) behind each felt oval, so the light shines through. Secure with tape or glue.
Build the wings. On cardboard, draw a bat-like wing shape—a wide triangle with scalloped edges. The wing should be about as long as your arm from shoulder to wrist. Cut out the cardboard pattern. Use it to cut two wing shapes from black felt. For each wing, cut two identical felt pieces. Place a piece of wire (or a pipe cleaner) along the top edge and the outer edge of one felt piece, then glue the second felt piece over it, sandwiching the wire. This gives the wing structure. Repeat for the second wing.
Attach the wings to the hoodie. Lay the hoodie flat. Position the wings on the back, angled slightly outward. The top of each wing should sit near the shoulder blades. Sew or hot glue the wings to the back of the hoodie. For a stronger hold, sew them with a needle and thread, or use fabric glue and let dry.
Create the tail. Cut a long, tapered tail shape from felt—about 2 feet (60 cm) long and 6 inches (15 cm) wide at the base, tapering to a point. Fold it in half lengthwise and sew or glue the edges together, leaving the wide end open. Insert a wire or a few pipe cleaners inside to make it bendable. Attach the tail to the back of the sweatpants at the waistband using safety pins or sewing. You can also add a small fin at the end of the tail, cut from foam, for a more dragon-like look.
Add the back spikes. Cut 5–7 triangular spikes from craft foam, each about 3 inches (8 cm) tall. Glue them in a line down the center of the hoodie’s back, from the neck to the waist. Space them evenly.
Make the belly plate. Cut a large oval from gray felt, about 12 inches (30 cm) long and 8 inches (20 cm) wide. Sew or glue it to the front of the hoodie, centered on the chest. Paint a few darker gray lines or spots on it to mimic Toothless’s belly.
Add the tail fins. Cut two small fin shapes from foam (like the back spikes but wider). Glue them to the tip of the tail, one on each side, so they stick out like a fish tail.
Paint the details. Use gray or silver paint to add subtle scale patterns on the hoodie and sweatpants. Dip a sponge in paint and dab it lightly to create a textured, scaly look. Let dry completely.
Final assembly. Put on the hoodie and sweatpants. Attach the headband. If you want, add a pair of black gloves and black shoes to complete the look. Adjust the wings and tail so they hang naturally.

Common Mistakes

Wings too floppy. If you don’t use wire or enough layers of felt, the wings will droop. Always reinforce the edges with wire.
Headband slipping. A smooth headband can slide off. Use a cap with a strap or add a piece of velcro to secure it to your hair.
Tail dragging too much. A heavy tail can pull your pants down. Use lightweight felt and only a thin wire, and attach it securely at the waistband.
Eyes not glowing. If the LED is too dim or placed wrong, the eyes won’t show. Test the lights before gluing them in place.
Spikes falling off. Hot glue can pop off fabric. Sew the spikes on or use fabric glue for a more durable bond.

Tips

Use a black hoodie with a zipper so you can take the costume off easily without disturbing the wings.
For a more realistic look, add a few small, angular white or gray patches on the wings and tail—Toothless has subtle markings.
If you’re making this for a child, use soft felt and skip the wire in the tail to avoid poking.
Test the LED lights in a dark room to ensure they’re bright enough. Battery-operated fairy lights are safer than glow sticks, which can leak.
Make the wings detachable with buttons or velcro so you can wash the hoodie separately.

Troubleshooting

Wings won’t stay up. Add a second wire along the bottom edge, or use a thicker gauge wire. You can also attach a small piece of velcro to the back of your hand to hold the wing tip.
Tail is too heavy. Remove the wire and use only felt, or shorten the tail. You can also attach it to a belt instead of the pants.
Eyes are not visible. Make the eye holes larger, or use brighter LEDs. If using glow sticks, activate them and place them directly behind the felt.
Spikes keep falling off. Reinforce with a few stitches through the foam and fabric. Use a strong fabric glue like E6000 (in a well-ventilated area).
Costume is too hot. Use a lightweight hoodie and sweatpants, and avoid layering. You can also cut small ventilation holes in the armpits (hidden by the wings).

Frequently Asked Questions

Q: Can I make this costume without sewing?
A: Yes, you can use hot glue and fabric glue for all parts, but sewing is more durable. For the wings, glue works if you use enough and let it dry completely.

Q: How long does it take to make?
A: Expect 3–5 hours total, including drying time for paint and glue. It’s a good weekend project.

Q: What if I don’t have a hoodie?
A: You can use any black long-sleeve shirt and black pants. Just attach the wings and spikes directly to the shirt.

Q: How do I make the costume fit a child?
A: Use a smaller hoodie and scale down all measurements. Skip the wire in the tail and use soft felt for safety.

Q: Can I wash the costume?
A: It’s best to hand wash and air dry. Remove the LED lights and any detachable parts before washing. The paint may fade over time.

Q: Are the LED lights safe?
A: Yes, battery-operated fairy lights are safe if the battery pack is secured and not near your face. Glow sticks are non-toxic but can leak, so tape them securely.
