Whilst we're on the subject of tails, I've seen videos where at the end of sewing, people use scissors to cut the tail but I've also seen people carry on the chain and bring it round under the foot for the knife to cut it. Yay or nay on that?
I used to and I still do if I'm doing samples. But an accident with some new trousers made sure I don't do it that way on a garment now! It,s so easy to take a chunk out of the fabric.
