why this one is worth making

  • It's budget-friendly and mostly made from recycled materials.
  • The pastel, sparkly twist makes it stand out from every store-bought astronaut costume.
  • Building it is a real hands-on engineering project — cutting, fitting, assembling.
  • The colors and details are completely customizable to your child's favorites.
  • It keeps going long after Halloween as playroom space-mission dress-up.

before you start

  • Measure firstMeasure your child's head before cutting the helmet. The opening needs roughly a 20–22" diameter circle on the bottom of the globe — measuring first saves you from cutting twice.
  • Adults onlyAll of the Dremel cutting and sanding on the acrylic globe is adult work. The tool gets hot and the acrylic melts and clumps the longer you cut.
  • Drying timeSpray painting the bottles needs light coats with 10–15 minutes of drying between each one, and the glued jetpack needs a stable spot to dry completely before you attach the straps.
  • Save your recyclingYou need two empty soda bottles and a cardboard box, so set them aside a week or two before costume night.
  • WorkspaceSpray paint outdoors or in a ventilated space, and keep a flat protected surface free for the hot glue and fabric work.
  • No-sew routeIf you'd rather not sew the jumpsuit, buy a metallic onesie or top and bottoms and add the embellishments with fabric glue instead.

the step-by-step build

Five phases, in the order they were actually built.

01

Create the Astronaut Suit

Metallic base, pink belt, stars and stripes.

  1. Start with a shiny jumpsuit or metallic leggings and a matching top. Pastel iridescent fabric gives it the magical finish. Use a zipper onesie or jumpsuit sewing pattern — the original fused two fabrics together so the suit has a purple velvet lining for warmth on Halloween night. Cut the fabric, fuse it with an iron, then follow the pattern. To skip this step, buy a jumpsuit or metallic top and bottoms and just add the embellishments.
  2. Add a pink ribbon belt around the waist to break up the metallics. The buckle is non-functional but makes it look far more realistic. Vertical straps are optional — they were left off here because the jetpack already has vertical stripes.
  3. Attach star patches, or cut stars from pink felt and glue or sew them onto the chest and sleeves. Silver faux leather stars were added at the elbows, small pink glittery stars on the chest, and long strips of silver faux leather were cut for stripes on the sleeves and pants. A NASA logo works too.

02

Make the Astronaut Helmet

The slowest part of the build — and the most impressive.

  1. Use a large clear globe or bubble as the helmet base. Mark your cut lines with masking tape or marker: a roughly 20–22" diameter circle on the bottom, plus the visor shape. Measure your child's head first — expanding the neck hole later takes far longer than cutting it right the first time. Pro tip: find a large dinner bowl that fits over your child's head, set it on the globe and trace it for a perfect circle.
  2. Cut lavender fabric strips to frame the helmet and secure them with hot glue or silver duct tape. Fold the stretchy fabric over twice and pull it tight. Smooth the glue as you go — clumps underneath show through. Do this on both the visor piece and the opening so no rough edges sit near your child's face.
  3. Make the visor hinges from cardboard and silver faux leather: cut a rounded triangular shape from a cardboard square, one for each side of the visor, cover both sides with the silver fabric and finish the edge with a thin strip.
  4. Attach the hinges with the two small bolts and nuts so the visor can pivot.

03

Build the Rocket Jetpack

Two recycled soda bottles become the boosters.

  1. Spray paint two empty soda bottles (silver, or white for a cleaner look — that's what was used here). Go slowly with light misted coats and let each one dry 10–15 minutes to avoid drips. A primer coat helps keep the paint from cracking. Wrapping them in metallic paper works too.
  2. Decorate the bottles with strips of holographic faux leather and small pink felt stars.
  3. Attach the bottles side by side onto a cardboard box wrapped in silver faux leather — this is the jetpack base. Use fabric glue or super glue, and set it somewhere stable to dry completely so the bottles stay secure.
  4. Glue pink bendy straws or tubing into the top of the bottles as "oxygen hoses." Pastel pink fidget tubes were used here; white or glow in the dark works too.
  5. Attach pink backpack straps so your child can wear it. Copy the looping pattern from a backpack you already own to make them adjustable — that way it still fits next year. Clippable claw buckles at the bottom make it easy to take on and off.

04

Add the Rocket Flames

Layered felt flames that move when they run.

  1. Cut flame shapes from pink, lavender and silver felt, then layer them together for a "shooting flame" look.
  2. Glue the flames into the bottom opening of the soda bottles.
  3. Let them dangle freely so they move while your little astronaut blasts off.

Final Touches

Suit up and launch.

  1. Put on the sparkly suit, belt and helmet.
  2. Strap on the jetpack.
  3. Add silver gloves or holographic boots if you have them.

Special feature

the best part: the rocket jetpack

Two empty soda bottles, a cardboard box and a few pink straps turn into the piece every other kid asks about. The bottles get light coats of spray paint, holographic strips and felt stars, then mount side by side onto a fabric-wrapped cardboard base. Pastel fidget tubes plug into the tops as oxygen hoses, layered felt flames dangle from the bottoms, and battery LED string lights tucked inside the bottles make the whole thing glow after dark.

  • Recycled bottles + a cardboard box do all the structural work
  • Adjustable backpack straps copied from a real backpack, so it fits for years
  • Claw buckles at the bottom make it easy to take on and off
  • LED string lights inside the bottles for a night-time glow

a few goodnightfox notes

the costume doesn't have to end on Halloween

Three easy ways the original tutorial keeps the space learning going.

Imaginative play

Space mission pretend play

Have your child pretend they're heading out on a mission. Ask where they're travelling and what they discover along the way.

STEM

Planet sorting game

Cut out paper planets and sort them by size, color, or order from the sun. Talk about rockets, planets and how astronauts live in space.

Movement

Astronaut training course

Build a simple obstacle course and call it astronaut training — low gravity, moon rocks and space tunnels.

astronaut costume questions

How do you make an astronaut costume for a child?
Start with a shiny metallic or holographic jumpsuit — sewn from a zipper onesie pattern or bought ready-made — then add a pink ribbon belt, felt or faux-leather star patches and silver stripes on the sleeves and pants. Add a helmet cut from a clear plastic globe and a jetpack built from two recycled soda bottles.
How do you make a homemade astronaut jetpack?
Spray paint two empty soda bottles, decorate them with holographic strips and felt stars, then glue them side by side onto a cardboard box wrapped in silver fabric. Add flexible tubing into the tops as oxygen hoses, layered felt flames at the bottoms, and adjustable backpack straps so your child can wear it.
What can I use to make an astronaut helmet?
A large clear plastic globe or bubble — a big ornament globe works well. Cut a neck opening roughly 20–22 inches in diameter and a visor shape with a Dremel, sand the edges smooth, then trim every cut edge with folded fabric so nothing rough sits near your child's face. Cardboard and faux-leather hinges with small bolts let the visor pivot.
Can you make an astronaut costume from recycled materials?
Yes — most of this costume is recycled. The jetpack boosters are empty soda bottles and the pack base is a cardboard box, which is a big part of why the build is so budget-friendly.
How long does a DIY astronaut costume take to make?
The original tutorial doesn't give a total build time. It does note that cutting the helmet takes the most time of any step, and that the spray-painted bottles need 10–15 minutes of drying between coats, so plan it across more than one crafting session.
