Mario Kart Family Costumes

So this year my oldest is 8 and I have a feeling that this is the last year we’ll be able to rope him into our family costume. So I decided to go all out and create Mario Kart cars to go along with our outfits. Pinterest had some great photos of the cars, but no tutorials, so I hope this saves you time and makes the process fun and easy.


  • Boxes:  I used small moving boxes from Home Depot for myself and my kiddos ages 2, 4, and 8. I used a medium moving box for my tall hubs who is about 6’4″.
  • Spray paint
  • Acrylic paint
  • Foam brushes
  • Blackcard stock
  • White card stock
  • White or grey crayon
  • Checkered streamers
  • Black sticker letters
  • Hot glue and glue gun
  • Giant rubber bands (These were right next to the boxes at Home Depot)
  • LED Push lights
  • AA Batteries (4 per light)
  • String
  • Duct Tape
  • Flat push pins and/or staples

I first tried to simply spray paint a box, but the cardboard sucked up the paint and left and see-through finish.  So I went down to the basement and raided the craft room for acrylic paint. I laid on a thick layer of acrylic paint with a foam brush and then sprayed the boxes with spray paint. I did both coats back to back because I was trying to get the painting done during nap time….God bless nap time, but I’m sure it might be better if you wait a bit in between coats.

While the boxes were drying I created logos for the front of the cars utilizing Power Point. Here is a link to the document if you’d like to use mine instead of creating your own. MarioKart

Next, I created the tires for the cars by tracing the LED lights on black cardstock. I used a white crayon to add a little detail so they didn’t look too plain.

Then I used yellow electrical tape to wrap around the edges of the lights to make them look a bit more realistic. I ran out of tape halfway through and painted the rest of the lights with yellow acrylic paint. Both versions seemed to turn out fine so use whichever you prefer or have at home.

Then I cut sheets of white cardstock in half and glued on letters to make license plates for the back of the cars. I then used hot glue to attach the logos, license plates and streamers.

Attaching the lights was a major pain in arse. I initially used hot glue to attach them, but my destructive 2 year old quickly showed me how easily they could be removed. So instead, I looped string through the back of the lights. Then I poked holes in the boxes and pulled the strings through. Then I tied both light strings together tightly multiple times to make sure they were solidly attached. If you can do without the lights, it will save you time and money, but my boys think the lights are the best part of the costume, so it was worth it this year.


Finally, I cut the rubber bands to each kids’ body and attached them with push pins. Then I completely covered the ends of the bands and inside of the box with duct tape. After then kids played with them for a bit, I further secured them with a few staples, because my kids are nuts and I don’t want those things falling apart while trick-or-treating.

Happy Halloween and I hope your kids get some great candy so you can eat it while they sleep!!
