DIY: Spongebob Squarepants costume for kids

I am writing this post in a state of sugar-overdose. Here are our this year’s Halloween costumes.

Halloween costumesDisclosureMy son wasn’t really interested in wearing a costume. This is the first year that he is aware of the link between Halloween and costume. We dressed him in this leopard costume when he was 5 months old. He had his CTA bus costume, which has half costume, half toy, last year. This year, I asked him what he wanted to be for Halloween and gave him few options. He refused all options except for Spongebob Squarepants. So I made this myself.


  • 1 extra large diaper box
  • Cardboard cutter knife / Utility knife
  • 2 big bright yellow poster board
  • 2 sheets brown craft paper
  • 1 sheet red craft paper
  • 1 sheet white paper
  • Glue
  • Markers


  1. Cut the bottom of the diaper box. Keep the top.
  2. Cut out head and armholes.
  3. Cover the top part of the diaper box with yellow poster board, middle with white paper and bottom with brown paper.
  4. Print out a big Spongebob face on a white paper and trace it out on the box.
  5. Cut out the eyes from white paper and tie from red paper. Glue them on.
  6. Complete the decoration with markers.
  7. You can support the shoulders with little towels.

My daughter is wearing the leopard costume sewn by my grandmother 2 years ago for my son. We used Simplicity Sewing patter for dummies, 0572, Pattern D. It has 4 pieces. Overall, had, shoes and paws.

Pin it for later:
