I made a play may for each grandson. One was train theme and the other was cars. For a "batting," I used something unconventional. I used 100% cotton mattress pads. Why? Because I wanted more cushioning for those little knees and I thought they would be more durable/sturdy than regular batting. Yes, it was a bit of a pain to quilt but I didn't have to quilt very densely since the pads were already "quilted". Those pads are 5-6 years old now and still in good shape. I sewed fabric printed like train tracks around the outside edge of one and pavement colored fabric (with satin stitch stripes) on the other so the boys would have a track for their toys. and yes, Grandma included a couple of trains/cars with the play mats.
