I don’t know what else to call these, but they remind me of worms. These are the little bits that are leftover after serging. I get these things everywhere. They are stuck in the carpet, to my clothes, on my children…they are everywhere. It is almost link an infestation. Don’t get me wrong…I wouldn’t trade serging for the world. I try to keep them picked up and nice and tidy, but they always make a break for it. So, if you are thinking about serging…beware of serger worms!
