Secure the chains of the beginning and the end of a stitch with your machine.

At the beginning of a stitch

1. Sew a few stitches, after chaining-off for 5 cm (2 inches).
    
2. Stop the machine and raise the presser foot.
    
3. Put the chains under the presser foot, and serge over it pulling toward you.
    
4. After sewing a few stitches, cut off the extra chain with the upper knife as illustrated.

   

At the end of a stitch

1. At the end of the seam, sew one stitch out of the fabric before stopping the machine.

   

   
    
2. Raise the presser foot and the needles, then reverse the fabric.

   

   
    
3. Lower the needles and the presser foot at the same position.
    
4. Serge over the seam, taking care not to cut the serged seam with the upper knife.
    
5. After sewing a few stitches, serge off the fabric as illustrated.

   

   
    
6. Cut the chain with scissors.

Method 2

With this method, the chains at the beginning and the end of a stitch can be secured in the same manner.
