This variety of stitch gives a wavy effect to the pattern and follows the same stitching pattern as the Laced running stitch.
|Back stitch: Lay the foundation by doing a back stitch|
|Fig 1: Take another thread and needle and bring it out through A. Pass the needle under the stitch A-B, from above, as shown. Do not pluck the fabric underneath.||Fig 2: Now, pass the needle under the stitch B-C, from below, as shown. Again, do this without plucking the fabric underneath.|
|Fig 3: Continue this process of taking the needle under each back stitch from above and below alternately.|
|Fig 4: The completed pattern would show up like this.|
Make sure that while taking the needle and thread under each running stitch, you do not pluck the fabric underneath. You can use a blunt needle to acheive this.
Make sure to leave the back stitch just a bit loose in order to allow the other thread to pass through it easily.
