I made placemats for kids for our church bazaar. I used children's novelty prints on the back, and brought the edges to the front as bindings around the chalk cloth. In the bindng on one side, I inserted two strings (made from the novely fabric). These were used to roll and "tie up" the placemat. On the otherside, I inserted a loop of elastic to hold a piece of chalk. I also put a piece of "pinked" flannel in each one for an eraser. They sold well!!
