Serged seams can be used on many garments. Your instruction manual may include suggestions for where stitches are used. Garment style, fabric selection, and personal preference will help you decide which seams to use. The serged seam alone is not always suitable for garment construction. Many seams are sewn using both the serger and the conventional machine. For example, pants, jackets, or garments requiring adjustable fit, or seams that will be subjected to a great amount of stress, should be sewn with a pressed-open conventional seam and overedged seam allowances.
