Is the insul-brite necessary? If you use 2 - 3 layers of w&n would that be enough?

Same here... I do use the insulbrite with one layer of warm and natural. It seems to be just right.

I'd love to know this also. :P

I use 3 layers of cotton batting.

My one and only potholder I made I just used one layer of
insulbrite and can't use it as it is not heat proof!
I'm going to be making more and plan on using 2 layers of batting with the insulbrite!
:-)

I am hoping to start working on my potholders this weekend. I really like the idea of making some larger for the casserole dishes. great idea.
thanks!

I only use insul-brite as well. I have never had any problems with this.

Where do you buy Insul-brite?

I can buy InsulBright by the yard at Wal-mart.

I have found InsuBright for purchase at Joann's and Hancock Fabrics in both packages and by the yard.
