Unicorn Costume with Light-Up Horn
I’ll be sharing my entire DIY Unicorn costume in another post, but below, I’m showing how I made the best part – the light-up horn.
Here’s a short video of how it looks in the dark:
DIY Lighted Unicorn Horn Headband Tutorial
- 3 Felt Sheets (1 stiff, 1 soft, 1 “pretty”)
- Multi-colored LED Lights (I used 2 strands)
- Glue Gun (or fabric glue)
- Thread / Needle
- Decorative Trim (I used faux fur)
I started by rolling this sheet of CPE Stiffened EasyFelt into a cone shape, and cutting off the excess pieces.
Then, I hooked the end of one of the LED light stings to the top of the horn. I rolled the cone shape around the lights, and stuffed the excess light wires into the horn.
Next, I traced the round opening on the bottom onto some of the excess felt, and cut out a piece to close off the bottom (with wings to tuck in and glue to the sides of the cone’s interior).
I glued the battery packs side by side to the bottom piece, then tucked everything into the cone and glued into place, making sure the ON/OFF switches were still accessible.
Next, I covered the cone shape with 2 more pieces of felt – 1 that was really soft and cushy, and one that was a little stiffer with pretty sparkles.
It’s important to make the inside piece slightly smaller than the outside piece so that the bottom/inside one won’t be exposed once you roll it around the cone (see the arrow below – that’s what you don’t want – I didn’t cut it down enough).
Next, use a needle and some strong thread to wrap very tightly around the horn. You want to create indentations with the thread.
I used the needle to secure the thread to the top, wrapped it tightly around the cone, then used the needle again to secure it at the bottom.
The strongest thread I had on-hand was gray, but if you have white, you may want to use that so it’s less visible.
Next, use your glue gun (or a fabric glue) to carefully cover thread with a pretty ribbon (pulling tightly as you go).
Next, you’ll attach your horn to either a hair clip or headband.
I added some gold glitter paper to this kitty cat ears headband from Charlotte Russe (which I already had on hand). Then paired it with a 2nd headband that has white fluffy ears.
I attached the pair of headbands together using a piece of leftover felt, then glued the horn to the felt on the top of the headbands.
Once the horn has been glued to a headband or hair clip, you can dress up the bottom with some trim. I used some faux fur from an old Santa hat.
Here is the completed headband with ears and the light-up horn:
