sorry I didn't get back saturday like I said I would DH had to put on a antivirus on my computer and get it up and running again.
About the insulubrite my sil said she got at Lowes. I looked and no one heard of it there also my Jo anns never heard of it or Hancocks so back to ordering on the computer. they never heard of thermalite nieghter
I also found out what SIL did get was thermolte. It is for using in clothing and gloves ect cause it retains heat. If you can find it I guess it would be good for things like casserole wraps or bun warmers for bread but I wouldn't use it in potholders or pads cause I thought the idea is to repell heat so back to the insulbrite stuff for me.
I thought maybe SIL knew more about stuff like that since she has been quilting for so long. I best stick to what I learn here for sure. LOL I should of known better and checked it out first after her directions put almost to Oklahoma when I first got here. Talk about the senic route home. LOL
