This is one thing that I have always done, (that is unplugging the iron) guess I learned this from my mom. Thanks Mom :D
I want to send a Huge Thank You for showing some pictures as to what can happen. My 9 year old is just getting into quilting and will be using an Iron (under my supervision!!). I showed him the pictures and he was like, What Happened!! I explained and he now has learned a very valuable lesson. So, thanks again for the pictures. They speak thousands of words!!
