Thanks to all of you wonderful board members, I have now started unplugging my iron every time I am done in my sewing room. I used to leave it plugged in all the time, but after reading a couple of the warnings members have posted, I now unplug it every time I leave the room and have the ironing board set up so that when I walk by the sewing room I can see the red light on the side of the iron and know at a glance it's still plugged in.
