Pink foam board from Home Depot, cut to fit around fireplace. I duck taped it together (underneath as well). Then, I covered it with quilt batting (folded to form layers). Lastly, I got some cheap fabric from hobby lobby and hot glued it underneath.
I wanted a stylish yet practical way to babyproof my fireplace hearth. I measured the hearth then built a frame out of pine to slide over it then used rubber pipe insulation to cushion the corners. I then wrapped it in polyfoam batting to add more cushion then upholstered it using tablecloth fabric that has a clear plastic coating so I can easily wipe it clean when sticky little hands touch it! Voila!
Fireplace Baby Proofing- Here is my quick solution to keep my newly crawling baby out of the fireplace! I cut and taped foam board to fit the size of the opening. I hot glued magnets to the edges of the foam board to hold it in place since our gas log insert is magnetic. I wrapped the foam board in fabric and hot glued the edge of the fabric to the back of the foam board. It really was a simple fix!
