Hello, and welcome from Michigan!

Hi and welcome from the sunny state of Florida!!

Hi from Ohio!

Stick with all cotton fabric and batting and you won't have any problem. Be sure your potato is wet when you put it in the paper towel. I cooked potatoes in the microwave before I had a bag and allowed 3 minutes, stuck a fork in and if it wasn't done, cooked it one minute more. My microwave has a setting for a potato that works fine for me. Sweet potatoes takes a little longer to cook in the bag.
Didn't know there was a special batting for a potato bag, will have to look for that.

Depends on the batting! I have one and my microwave is 1300 watts. Never a problem.

Hello and welcome to the board from Michigan. I am sorry about your potato bags catching on fire but it did give you inspiration for a cute board name!

Welcome! I just used my potato bag the other day and have never had a problem with it. And I have a high wattage over! Mine was not home made but bought for me as a gift from a "regular store". Not sure what's in it but so far so good. However, I won't walk away from it while cooking now.

Potato bags are supposed to be 100% cotton, from fabric to thread, and should be prewashed before construction to get the sizing out of the fabric. That is what is flammable.polyester is also flammable And of course you never start cooking anything in the microwave and walk away, no matter what you are cooking or what you are cooking in
