I want to make a pressing mat (ironing blanket) to take to classes and retreats. My plan is to sandwich batting between 2 pieces of fabric (probably unbleached muslin) and bind (or maybe just serge) the edges. I have some Insul-brite that I plan to use for batting, but it just doesn't like that will be enough protection for the surface underneath when using a hot iron on it. I plan to put at least one thickness of Warm'n'White batting in it, too. How much Warm'n'White do I need? If I use more than one thickness, do I put the Insul-brite in the middle, between the layers of Warm'n'White? I've never used the Insul-brite before and need some guidance.
