DIY Batman Cape and Robin Cape For the capes, I used this tutorial.
I thought about buying their costumes, but I decided that I wanted to try and make them.
Thats how wide I got it.
And they have some good ones out there that really do work.
Reinforce any strings holding a mask on your head with tape to prevent the string from ripping through the mask.
Place the bag over the top of your head making sure it does not cover your eyes mouth or nose.
This makes it safer as well as cooler, according to Aidan.
