With my SIL we purchased a serger between us and decided to go on a days class together. She ended up with an interview day of class so my brother went with me so somebody in their house could work the machine. Never again. I have sewn all my 50 years of life not him he could use a sewing machine. During the day the other ladies Sid don't bring him again. He was far better than any of us. On the trip home asked him why he was so brilliant at it. Answer he looked at it as a machine not a sewing machine . Since then I've done the Same still not as good as he is.
