/cgl/ - Cosplay & EGL

My friends and I want to do a group Sinister Six cosplay and I'm trying to make a Lizard tail. The idea I'm having right now is to use a pool noodle filled with sculpting wire, and wrapping it in a fabric that has a reptile skin pattern on it. I want it to be semi-poseable (hence the sculpting wire) but I also need to make it lightweight enough to make that possible. I was previously using a leather fabric, but I think that's been making it too heavy and causing it it "droop". So I'm looking for a new fabric or any other tricks to make the tail lighter as a whole.
Though, if anyone has a better idea than this pool noodle thing, I'm open to starting from scratch.
