I use only Insulbrite, not poly as will melt. Love to make also trivets out of it...but would recomend two layers.....
In the product insulbrite the secret is the foil.....for I suppose you could make your own if you were so inclined.

I also use old towels cut up. Do not use Poly it will not protect against the heat and may get melty. I also use insulbright and one layer of cotton batting. Make up a couple of samples of the materials you have access to and test them out, then use the winning combo. There are several combinations that work for me, try out your own.

Definitely add a layer of insulbright... this is a great product, you can even add more batting for better insulation... definitely use cotton to avoid burnt fingers. I have read of people using old bath towels to bulk up the insulating ability.

ditto. and insulbrite also

Put the poly batting between two pieces each of the cotton batting pieces. That will make a pretty thick hot pad, but I like them thick as long as I can fold them froggyintexas

Polyester batting will melt and might cause some nasty burns. I think 100% cotton batting would work, but I would use 2 layers for more protection from the heat.

Insulbrite also melts if a hot iron is set on it. Or more accurately, the white part that I think is polyester.

I used 100%cotton batting with no chemicals for my microwave baked potato bags, I would use the same for pot holders... not polyester!!!

Buy an army blanket (wool) at an army/navy surplus store and cut into squares to use for filler. That will protect your fingers and the wool will last for many years.

I've always just used scraps, usually poly. works fine. lasts for yrs.
