Electronic sewing machines have more functions than a mechanical sewing machine. Some features of an electric machine include the ability to automatically cut the thread and to automatically adjust the tension and stitch length to fit the needs of a particular project. This saves the sewer time and frustration. Electronic machines may also automatically sew buttonholes when the desired size and shape is input into the machine.
These types of machines are more efficient than mechanical types because they are run via electrical impulses to control the speed and accuracy of the stitching. Mechanical machines, on the other hand, rely on mechanical parts only, making them essentially no more than a manual machine run on electricity.
Electronic machines are ideal for the amateur home tailor who has more than rudimentary knowledge of the art of sewing. If planning to use the machine on a semi-regular basis or for more elaborate projects than basic hemming, an electronic machine is the ideal choice.
