Frequently Asked Questions

Can Insul-Bright be used in the microwave? NO because of metalized fiber. (Pellon makes a cotton quilt batting for the microwave called Wrap-n-Zap.)

What temperature will this product withstand? Potholders made with this product can go up to 400 degrees.  If your oven temperature is warmer, just use a couple of potholders to be on the safe side.

Is there a right side or a wrong side? If you are using the woven batting there is NO right or wrong side.  If you are using an insulated batting with a clear visible metalized side called Therma-Flec, that would be the side you use to pick up your hot or cold items with, and you can cover the other side of batting with cotton fabric.
