I have a HUGE 54" roll of thicker batting given to me. It wonderful however I have no idea if its poly or cotton. I normally use the cotton that is pressed very thin and feels like "felt"? I read many posts on potholders. Some say yes you can use poly one said no, most were yes/no.. so curiosity makes me wonder.. I opened up one of my old potholders and it looks just like this stuff.. its not thermal yet worked fine in my old holder. So how to know? I know the poly/cotton test with a match but think batting.. it might not work the same? ARGH.. I am sure there is an easy answer.

ps the fabric I am using is 100 percent cotton only.

Batting with poly will let the heat escape up and to your hands quicker then a dense cotton batting.

Is it really lofty? The cotton poly blends 80%cotton 20% poly I have seen resembled regular cotton batting...

The first potholders I ever made I used poly batting. You can fold use two of them together and folded in half and it's still not enough to keep from burning your hands! Use all cotton! I used two layers of request weight Quilter's Dream in the next set and they're very nice potholders.

Cut off a small piece of the batt and burn it. If you get all soft gray ash it's 100% cotton. Any hard black lumps and it has some poly.

use it for a quilt and get Insulbrite for potholders. I've made many, many potholders with it, and love it. You only need one layer and nothing else and they can really with stand a LOT of heat....
