I was able to find special batting, if that's what it's called from my local fabric store. It comes in a couple different shapes to go with whatever mat you're making. You can also buy it in a long form so you can cut to fit whatever you're making. It's perfect if you want to quilt on it but all I did was use some of my decorative stitches on my machine as I was using 4 different fabrics (scraps) to make the placemat.
