It has no poly scrim but is thicker than the recommended batt. Yesterday Joann's sold me a small batt of Warm and Natural Needled cotton batting as 100% cotton. When I got home in better light, I saw tiny print on the bottom of the bag's back that said 12.5% polypropylene! Makes me concerned about buying things at a craft show to be used in the microwave. Any thoughts?
