A question about constraction capes

[Onepu the Protector]

My friend wants to make a custom hood for the Kylo Ren figure but he doesn't know which material he should use to make it match the official capes, so I decided to post this question here for him. What kind of fabric are the capes from the Lego Action Figures made of?

When I make capes I use broadcloth. I then treat it with anti fraying solution (one coat) and clear nail polish (one coat). This gives a feel and texture that's almost identical to the stock Lego capes.
