Who does extreme ironing People all over the world who like danger do it. There are about 1000 people around the world who do extreme ironing. There are extreme ironing clubs and groups in Britain, Germany, South Africa, New Zealand and the United States. You don’t have to have any special qualifications(资格证明)to do it. In fact, anyone can do it. However, it is better to start ironing in your back yard(院子) before you start to iron on top of a mountain.

There are, of course, some rules in extreme ironing. The ironing must be outdoors. You must take an iron, an ironing board, and something that you actually iron to get the wrinkles out. Outdoors includes faraway and unusual places, such as on top of a mountain, while skiing, snowboarding, skydiving, or under water. There are no limits. The more unusual the better. However, you should plan carefully because weather conditions can suddenly change on mountains, for example. You should not do extreme ironing on your own.

What kind of things should you have Your must have a real iron. Travel irons are acceptable. You must not use plastic or toy irons. The clothes you iron must he at least the size of a hand towel.
