I'm wanting some suppressor wraps but WOW are they pricey. I've got a grandma who can do just about anything with a needle and thread and would be thrilled to have a project to take on.

I can buy small pieces of Nomex (or similar material) for the exterior. Fire resistant thread is easy to find as well. The question I have is what would you use to insulate it and/or put on the inside?

My original thought was to make a "sandwich" of Nomex-Welding blacket-Nomex.

What say you?
