I made a sew of microwave bowl holders after Christmas just for fun. I also made a pattern for myself suitable to use to hold a large plate. I had not heard of them catching on fire before I read it on this site. Used the batting sold for these items. (Saw the batting at a good price at Walmart the other day.) However, I don't think if you are warming something up for a minute of so there would be a problem. But just in case I now warm up the food and pull the item onto the holder. Works for me. Love using them. Great for that bowl of oatmeal in the morning or leftovers at noon.
