My neice's cosy caught fire. It was made from 100% cotton everything. But it had food residue on it. We think that is why it caught fire.
I would not sew anything metal onto the cosy because there will be someone somewhere that would still put it in the microwave and cause a worse problem. Maybe one of those signs with a microwave in a circle with a red line thru it sewn into the bottom?? I'm sure there would still be people who would not get the message.
