Pekinese stitch also known as Chinese stitch since it is to be found in Chinese embroideries.
It was worked in silk, on a small scale, row upon row in blended shades to fill shapes.
In old Chinese embroideries this stitch can be found worked 30-40 stitches to the inch.
When worked on a larger scale Pekinese stitch creates a braided line.
First work a foundation row of back stitch in a fairly loose manner because the threading will tighten them.
A second contrasting thread is then threaded as illustrated. To create a neat textured line take care to tighten slightly after each threaded loop is created. As you move from stitch to stitch do not pass the needle through the ground fabric. Use a blunt ended tapestry needle for this part of the process to avoid splitting the foundation stitches.
The thread that you use to lace with, can be a metallic or fine ribbon. Experiment with contrasts of texture and weight.
