Check out this totally fun, quick to make and inexpensive Easy Unicorn Halloween Costume! All you need are a few items from the craft bag…you know, the one that you prepared using our free list (or Amazon links) so that you can do all of the crafts here at “In the Bag Kids’ Crafts” at the drop of a hat (or horn…get it?). I hope this makes spending quality creative time with your kids so much easier and more do-able!

  • Paper plates (9″ coated)
  • Clothespins
  • Medium pompoms
  • Newspaper
  • Glue stick
  • Elmer’s glue
  • Variety of paint colors (of your choice)
  • Hole punch
  • White yarn

Step 1

  • First, cut about 3 inches around the outside of 2 plates (more if needed)
  • Next, cut these edges into pieces. Start with a piece that is about 6 inches and make each one a little smaller.
  • You should end up with at least 6 pieces. Though you can make more if you would like a larger horn. Exact measurements are not necessary.

Step 2

  • Place the pieces on the newspaper to control the mess
  • Pinch the pompom with a clothespin to make a “paint brush”
  • Paint each piece of the unicorn horn a different color
  • Allow the paint to dry thoroughly

  • Use a clothespin to hold it shut until the glue is completely dry

Step 4

  • Stack the cones on top of each other in size order and secure with Elmer’s glue. (Watch for drips)
  • Once the glue is dry, punch a hole in each side of the base of the unicorn horn.
  • Tie a piece of yarn in each side

Once the unicorn horn is complete, the most important part of the costume is ready to go. To complete the costume, here are some ideas:

  • Wear all white
  • Put some streaks of color in your hair and wear it down or in a pony tail
  • Use face paint or make-up, especially around the eyes, to add color
  • Complete the costume with a tail. You can either make it or use a pompom like this one:

If you would rather make a unicorn tail, follow these instructions. But just increase the size of the cardboard to a piece that is as big as you want the tail to be. You can make it all white or use a rainbow of colors that matches the horn. This may take almost the entire skein of yarn. So, be prepared.

I would absolutely love to see your finished product! Please let me live vicariously through you since my boys are too old now for Halloween costumes 🙁 Send pictures of your kiddos in costume to hello@inthebagkidscrafts.com or tag me on Instagram.

Save this for later. Pin it to your favorite Pinterest board…
