insulbrite
I am making a casserole carrier that calls for insulbrite, Can I quilt the three layers being that it is insulbrite wouldn't the tiny needles holes take away affect of the thermal meaning the heat escaping through the stitching, and if I don't quilt the layers I'm afraid I am going to have a bad mess when it is washed, the fabric are prewashed not the insulbrite, what are your experiences with this? thanks
