i haven't sewn any clothing yet but had to explain to the hair stylist what happened to my bangs once. I have to sew with out my glasses now so I have my head real close to the machine. I was sewing on a old new home and the thingy that goes up and down that the thread is fed through ate the front of my hair. the only way to get it out was to cut my hair, it ended up pretty short and a mess. Now I make sure I have a headband on LOL.
