I teach 4H sewing. I keep an extra sewing machine on hand in my car. Gremlins. They like to get in the kids machines when youre not looking. I had 6 girls and only 1 machine working one night. Now I keep an exra machine handy. I just asked at church if anyone had a machine they were thinking of getting rid of and why I needed it. I got two. My dad went over them, gave him something to do. Clean and tuned them, nothing wrong with them and I have backup. Saves a lot of tears from the kids. And me.
