Style M measures 1.023\" across and 0.435\" tall, against 0.815\" x 0.465\" for a Class 15. That extra capacity is why it is used both on longarm quilting machines and on medium-to-large industrials working canvas, upholstery and leather — fewer bobbin changes.\u003c\/p\u003e\u003ch4\u003eDoes the bobbin thread have to match the top thread?\u003c\/h4\u003e\u003cp\u003eNot necessarily the same brand, but it should be the same fibre and a similar size. Mixing polyester on top with nylon underneath gives you two threads that stretch and shrink differently, and the seam puckers or the tension drifts.
