I have a big steam Rowenta and TWICE I left it on all night. I purchased a timer at Walmart and plugged it into the iron. I can set it to stay on all the time, or up to 60 minutes in 5 minute increments. It will never get left on all night again. My worst habit is not cleaning up after each project and having an unbearable mess...not being able to find the scissors, etc, because they are buried under piles of fabric. I wish I could be more organized.
