I use scrap all-cotton batting. I quilt each side with a layer, then put those two together and bind, making a loop at the center of one side or at a corner, depending on how I want it to hang. One layer of batting is not heat resistant enough for me.

I use batting scraps, two layers. They work fine, never been burnt yet.

I used up the batt in an old Ironing board cover. Works great and is less expensive. I like them thicker so I doulble it up.

ditto, insulbrite and a layer of batting for it looks quilted when i quilt it.

I use all kinds of stuff , two layers of old terry towels, a couple of layers of old sweatshirts, old felted sweaters, a couple layers of batting scraps.
I hate the idea of buying something for such a ultility type project. the only thing I concern myself with is getting the right thickness ( so they are useful) and using the right ones for each , so you can't see the middle contents.

I'm getting lots of good ideas on this thread. I'm working on my potholder now!

Is there a website to buy Insulbrite? I just did a search on http://www.warmcompany.com/ibpage.html, but they didn't list anything in Texas. (slight confusion on my part...)

I like to use InsulBrite. I use 4-5 layers of cotton, one of Insulbrite, channel stitch on the bias then cut thru all but the last layer of fabric. Then was and dry before binding. I guess it is called a chenille method. I usually have enough fabric left from an apron to make a matching potholder. Only the bottom layer really shows what the fabric really is.

thanks for the link, cool potholders

I use insulbrite and warm and natural batting

Super easy!
