One of the most common techniques in garment sewing is the understitch.  You tend to find understitching done on garments that have facing or sometimes on lining.  Facing is usually found  in garments that are sleeveless or collarless.  Regardless of where the understitch is going, the process is always the same.  The reason for understitching is to keep the facing on the inside of the garment so that it won’t roll over to the right side of the garment and play peek-a-boo with you.  It also add stabilization to make turning the facing or lining easier and more crisp looking.  Once you make the understitch, you will find that facing should fold over neatly and your garment will look more professional.  Check out our new tutorial and we’ll show you exactly how it’s done.
