Flamed Headliner

Hey, im just wondering if anyone out there can give me some step by step instructions on how to make my reg-cab 95 s10's headliner flamed.I pulled the headliner out, im just wondering if i need to strip the old material off "which is still in great shape" or what. I also need to know what kind of materials to buy, like what kinda foam for the flames, and what kind of material to recover the headliner in.

Any help is appreciated

Thanks
