Upcycle Mylar balloons for the inside of potholders?

[Poundwise]

I just cut down a bundle of deflated Mylar balloons... I'm aware that one can reinflate these for reuse, or cut them up for wrapping presents, but these particular balloons have leaks (I tried reinflating them already) and they are too wrinkled and scratched to be used for presents.

I recently sewed some potholders using a material called Insul-Bright which "consists of hollow, polyester fibers needlepunched through a nonwoven substrate and through a reflective mylar. The needled material is breathable and won't break down with washing. The hollow fibers resist conduction while the reflective mylar resists radiant energy."

Can anyone think why I couldn't just cut up the balloons into squares, and sandwich them in between layers of polyester batting and cloth to make some thrifty heat resistant potholders?

I wouldn't use polyester batting; use cotton to avoid melting and problems with steam.  Even Insul-bright recommends using an additional layer of cotton when making pot-holders or oven mitts.  You might also need to quilt it to avoid shifting.

Thanks geekette! I automatically quilt potholders.  I forgot that the potholders I made were:
cloth
old cotton terrycloth towel
Insul-bright
more terrycloth towel
cloth

So using an old balloon it could be:
cloth
old towel
poly
mylar
towel
cloth
