I made tater bags with cotton batting several years ago, all went well, but then last year when I saw the new cotton batting made for potato bags I bought it & made several for presents-made sure all cotton material, even the thread! I used the one I made for me to try it out-it caught on fire. Very scary, obviously did not give out the others for presents, still trying to use them for something else, jewelry bags, kindle bag, etc.

OK, all this talk about what not to use but what are you supposed to use? This isn't a subject that I am familiar with other than having read about the fact that some of them have caught fire. I just received two microwavable bowl wraps as as a gift today and would like not to have to deal with the possibility of a fire.

I made the microwave bowl potholders for Christmas and myself. I've had mine in the MW for 4-5 min. And no problems. Potatoes are generally in there longer so maybe that's where the problem lies? I personally just wash, poke holes and then zap my potatoes in the MW. And after i heard that you don't have to wrap foil around the potatoes before they go in a regular oven, I was real happy about that too. Just a pain! LOL
I think a convection oven is hotter than a MW oven. I don't think i would use the potatoe bags in there. Isn't it like a regular oven with a fan circulating the heat so it cooks faster?
Walmart.com has wrap n Zap for $3.09 per pkg. FYI

Wrap n Zap by Pellon is an all cotton batting. It is thinner than Warm and natural and doesn't have a scrim on it. Then use 100% cotton fabric and thread. That is what is supposed to be used. I think people get in trouble when the proper materials aren't used or not used the way they were intended.

I just nuke them naked and when they come out I wrap them in a towel for 5 minutes.

You cannot use insulbrite in the microwave. It has aluminum in it. To make the potato bags you need to use "Warmtator" batting. You have to use all 100% cotton-fabric, thread and batting...

great save!!

I have the same question as Cannyquilter - why would you wrap your potatoes in fabric and batting to cook it in the microwave?

Count me as another who wonders this. I stab mine and stick them in the MW naked. They come out perfect. IMO, it's just a make-work project. Why do people embroider on toilet paper?

I'd had mine for a while, not used much, but did use it and it caught fire....WOULD NEVER EVER make or recommend the use of one of these.....who knows the correct way to make them anymore with all the mis information out there!!
