I was busy sewing along on my serger when suddenly a section of already-serged fabric somehow popped over the cutter and bent the heck out of my needle. Can you see that? It was so loud and unexpected, it scared me to death.
Thankfully, it was a quick remedy. Well, the replacing of the needle was quick. Having to re-thread and make sure everything else was okay took longer.
Have you had any moments when sewing has gone bad?
