I got a very bad burn on my fingers using a potholder with poly-fill that I didn't know had gotten wet. I was taking a pan out of the oven.

Everything I have read says NOT to use poyester batting but double layer of cotton batting along with the Insulbrite. Also read something yesterday that said not to use the Insulbrite in the microwave to heat up potatoes or corn.

I use one of insulbrite and one of warm and natural. I remember reading awhile ago that cotton batting was better to use. I have burned one and the cotton and insulbrite worked. I survived.

I used 1 layer of insul-brite and 1 of Hobbs 80/20. Works ok for potholders but I'd use another layer of Hobbs 80/20 for a trivet or oven mitts.

Just for another point of view I use blanket offcuts made of 100% wool for my potholders. I am able to buy offcuts from a local blanket manufacturer and like wool because it's a naturally good insulator.

Insulbrite will ruin a rotary cutting blade. I use an old worn out blade or my craft scissors to cut it. I found a piece of heavy duty aluminium foil sewn between cotton batting works just as good and it's much cheaper.

Thank you for the information. God bless.

Thanks for the info!

I always recover my old potholders with orphan blocks. They become very thick and make the best potholders I can hold a hot pan for a long time if need be.
