I am making some hot pads for wedding gifts, and I have some ironing board fabric (the silver stuff that isn't necessarily fabric). If I were to use this, would I layer it between my two layers of batting and which way would the silver go? I usually use 3 layers of cotton batting or two layers with a piece of flannel in between. I cook with a lot of cast iron, and I like thick hot pads. I am also making some for myself, because I am replacing mine. Also, have any of you used the insul bright and if so, would you still add some cotton batting?
