Chain stitch can be used not only as an outline / border stitch but also as a beautiful filling stitch.
This is the traditional method of stitching the chain stitch. There is another method to make the same stitch. It is called reverse chain stitch.
Other names for chain stitch:
Point de chainette
Chain stitch is the most popular stitch for embroidery lettering, curves and lines. It is also stitched in close rows or in spirals to fill an area in embroidery design.
Composite stitches can be made by stitching chain stitches on a base made with other stitches (example straight stitches). Similarly, chain stitch can also be a base over which other stitches are stitched.
Pierce the fabric and bring the needle up.
Pierce the fabric at the same spot again and bring the needle up a short distance away. This distance will decide the length of the chain. Before pulling the needle away, loop the thread under the tip of the needle like shown below.
Chain will form when the thread it pulled. If it is pulled too tight, the chain will be a tight chain and it will be difficult to make the next stitch.
First chain is formed.
Now repeat the same step to stitch the next stitch.
Pierce the fabric and go down at the same spot where the thread is and come back up a little distance away.
Loop the thread under the needle and pull the needle to finish the stitch.
