Oldpiglady, Welcome back and so sorry about your house fire ,but double happy that you caught this iron before it
caused more damage. I always unplug things may even start unplugging this thing also. When I was small our home caught fire from a chimney fire that scared me so bad that through life I've been over concerned about fires. Don't think I would buy another Hamilton Beach iron. Don't think it's the quilt your making just a coincidence, thank God you caught it in time.. Happy quilting
