I had built one for my MSR Titan Tea Kettle. It's a simple, insulated pouch with a drawstring top, that serves as both a cozy and as a bag to carry the pot with stove, lighter and misc cooking stuff inside. It's made of a light ripstop cotton duck, and insulated on the side and bottom with Insul-Bright, a hollow polyester fiber with a metallized film backing.
It's over-built, and I figured I could get away with a lighter material. I still wanted cotton, cause I didn't want it to melt from a hot pan. I broke out some scraps from a Ski Patrol project, the leftover Insul-Bright, and Mary's sewing machine.
