We have a home that has a huge floor to ceiling stone fireplace. We also have a baby that will be crawling soon. The fireplace has a seating area also made of stone. How can I cover the bottom part of the fireplace so that it does not pose a danger to the baby if he should fall back against it or bump his head? Is there a way to apply adhesive to cushions that can be glued against the stone? May seem like a silly question, but I am desperate here! Thanks!!
