I know this is like...SUPER old. but thank you. I didn't have all of the needed stuff so I had to rely on my steady hand and some paint but it still came out good.
You have no idea but you're a lifesaver
You can substitute the electrical tape for whatever you want. Its not visible when you wear it, since it's on the inside. However the foam is really cheap and you can get it at any art or craft store. It has clean edges when you cut it and it's more rigid than paper so it will look better. It's also thick. I would not recommend substituting it.
Bet your guys' headphones don't smell like Twinkies, lol! I used a Twinkies box for the curved part, so it actually does smell like twinkies.GREAT! NOW I'M HANGRY at myself for using the Twinkies box because it smells so yummy! Anyways, Awesome tutorial! My cosplay would have been doomed (and I would've been broke -__-) without this tutorial.
