Even if the sewing machine you own has a wide throat space and works at a fast speed, you need a specialized quilting machine. You can do quilting jobs with a standard machine. However, a specialized quilting machine will not only have a wider throat space and a fast speed, but it will also allow free-motion stitching along with straight-line stitching, which is needed for quilting. So, for best results and an easy quilting job, it is wise if you get a specialized quilting machine.
