I just found out about this batting made for the microwave potatoe bags. I haven't seen it in any stores yet.

Interesting!!! It looks like Warm and Natural...I read that it will be out the end of June,

I wonder why a special batting for these bags? Is it because it is "untreated" due to using it with food?

I was wondering that too but I thought maybe it's because there's been stories of them catching fire.
A friend of mine uses one of those bags almost everyday and never has had a problem with it.

This new batting will not be available until the end of June 2010. if you open the web site it tells you that right at the top.
This batting looks great to me, I wouldn't mind trying it.

Warm and Natural cotton batting and other cotton batting has scrim. Scrim is a very think poly layer and poly is what catches on fire in a high wattage microwave. If you microwave is around 800 watts it think the regular batting is fine. Put a piece of any batting you want to use for the bag in the microwave and test it for the length of baking several potatoes. I wrap my potatoes in a cotton feed sack towel if I use the microwave. Not as pretty but works fine.

thanks for the information

I keep hearing that certain plastics aren't good in the microwaves, too. The heat releases chemicals that aren't good for us... poly is a type of plastic I believe....

I think I may just make cotton bags without any batting in them for tater bags :D:D:D

Cool, thanks for sharing.

I made one last month and just used 100% cotton batting sold at the quilt shop. We also used 100% cotton thread. Be sure and mark your bobbin so you know which one to use when you make your next one.

I wondered about these. I have tortilla warmers that have some sort of plastic in them. I wanted to make some, but wasn't sure what they used. I hand washed them and the fabrics bled all over the place. I wonder if you really need the plastic wrap inside (there was batting in it too). I might try this batting for the tortilla warmers. I did read that everything in it needs to be 100% cotton. But I'm sure there's plastic sheeting of some sort in my tortilla warmer that I purchased at the Del Mar Fair.
