I just made some potholders using insulbrite and and old wool sweater as the batting. tested it and works great. I used both the insulbrite and wool (or warm n natural on a few); BOTH on the heat exposed side of my oven mitts and I am satisfied that I won't be burnt! The other side was the quilted material and I just lined it with warm n natural. My sis thought it was overkill but, I took a roast out that had been on 400 and it was not a problem.
