/cgl/ - Cosplay & EGL

Wow, been a while since I posted on this side of the website. It actually looks civil now compared to years ago.

Anyway, trying to put together pic related, and although this isn't really for Halloween, I figured this is the best spot I could find for advice on it. I have a black costume cape that I've had for a few years and I wanted to convert it for use in this, saving funds and all that. I figured with standard red dye the colors would end up matching the dark red necessary anyway, because lol color science or whatever. Problem is, the cape itself is polyester, and apparently most dyes don't like the polyester.

So, is there a way for me to dye my cape to the red that I need without damaging it, or am I just gonna have to bite the bullet and find a new one/make my own?
