Sometimes I think I'm a slow learner!
I like to put a crisp fold with my steam iron in bindings or thin edging, but I get really tired of burning my fingers. I tried using a stylus etc but these things don't come naturally to me. But today...Eureka! I turned my iron around and ran it BACKWARDS down the fold. I could get my fingers within half an inch of the sole plate and not get burned.
It worked for me.
