Thread Tension and Bobbins
Wrong tension is behind more ruined seams than any other fault on a home sewing machine. This section covers the whole thread path: the tension discs and dial up top, the bobbin case and its tiny screw below, and the loops, puckering, and nests that show up when the two fall out of balance. You will find guides for reading your stitch like a technician, setting top tension by number, adjusting bobbin tension without wrecking the case, and matching settings to thread weight and fabric. Each guide gives exact starting points, the order to test in, and the signs that tell you which side of the machine is really at fault. Start here when your stitches loop, snarl, or pull.
