A serger is a special-purpose sewing machine. It cuts sewing time considerably, because it trims and overcasts raw fabric edges as it sews the seam. In addition, it performs this three-in-one operation at high speed. As another benefit, all fabrics feed evenly so that even traditionally difficult-to-handle fabrics, such as slippery silks and thin sheers, will not take any extra sewing time.
A serger eliminates time-consuming steps and encourages efficient sewing habits such as flat construction, pinless sewing, and continuous seaming. It also dispenses with routines such as raising and lowering the presser foot, backstitching, and filling bobbins.
A serger excels at making self-finished narrow seams, rolled hems, blind stitched hems, and overcast edge finishes. It is also good for applying elastic, ribbing, ribbons, and lace.
