When you sew there is a starting and an ending point. Have you ever had the seam start to unravel or the thread come loose so the stitching shows as lines of thread at what is supposed to be a seam? Learn to back stitch or lock stitch to secure the beginning and end of your sewing to prevent them from unraveling or from the stitching loosening up and stretching out of shape.

Back stitching is done by sewing backward and forward at the beginning and end of a seam, on top of the seam stitches to prevent the stitching from coming undone. If you are sewing with a very fine fabric you may not like how back stitching leaves a relatively large amount of thread that can show through fine fabric, or change the way a fabric will drape or hang. In those cases you want to use a lock stitch.

In some cases it is best to sew off the fabric, leaving a long tail of thread and then knotting the thread. Sewing a dart is an example of using this technique. Back stitching or a lock stitch would leave an unsightly lump at the pointed end of a dart, but sewing off the end of the point allows for a smooth transition. What is a Dart and How to Sew Darts
