"Smoldering iron" seems somehow appropriate for what my mum used to do to my clothes with her old iron.
A little off topic, but I had some friends who were messing around with an iron one day (!?) and, thinking it was cold, one guy bared his chest for another guy to stick the iron on it. I don't know why. Years later he still had the scarred imprint of an iron down the centre of his chest and stomach. Of course, we all called him The Iron Man.
Had this other friend who had a fetish about ironing his clothes. He'd take an ironing board and iron with him whenever we went anywhere. He was the lead singer of our band for a while and we'd all go away for a gig, crash on someone's floor for the night and get up to see him ironing away. He'd re-iron already ironed clothes, the mad git.
Ok, I'm done rambling.
