A full astronaut costume can be expensive. These crochet accessories transform a white sweatsuit into a space-ready ensemble for a fraction of the cost.

Materials

  • Worsted weight yarn: White (300 yds), Light Gray (100 yds), Silver/metallic (50 yds), Red and Blue (scrap for patches)
  • Size H/5.0mm crochet hook
  • Polyester fiberfill
  • Clear vinyl sheet (for helmet visor, optional)
  • Yarn needle, scissors

Step-by-Step

The Space Helmet

  1. With white: Magic ring, 8 hdc. Increase 6 sts per round until circle covers the crown (approx 7-inch diameter for child).
  2. Work even in hdc until helmet reaches the jawline.
  3. Face opening: On next round, work 20 sts, ch 20, skip 20, continue around.
  4. Continue working even on remaining sts (the back and sides only) for 4 more rounds.
  5. Visor rim: Work sc around the face opening with gray to define the edge.

The Mission Patch (Make 2–3)

  1. With blue (or red): Magic ring, 10 sc. Increase by 6 sts per round to desired patch size (approx 3 inches).
  2. Embroider a star, rocket, or mission name using surface stitching with contrast yarn.
  3. Sew patches onto the chest and sleeves of the sweatsuit.

Jetpack Straps

  1. With gray: Ch 8. Sc in 2nd ch and across. (7 sts)
  2. Work in sc until each strap is 30 inches long. Make 2.
  3. Sew straps to a cardboard box covered in silver fabric for the jetpack, or wear them crossed over the chest as costume detail.

For the full look: pair with white boots, silver gloves, and an American flag patch.
