Melted cotton, Martina? WOW! You are fortunate it didn't start a fire in your home. Roy used to be annoyed with me leaving the iron plugged in and on all day while I was sewing but he gave up nagging when I pointed to all his electrical taped gadgets.
I'm going to look at a smaller iron, burned my arm last month when I had it near the sewing machine while putting blocks together. :roll:
