This stitch is so called because, each loop in the chain is formed by using the process to make a knot. The loops formed are circular in shape unlike the ‘almond’ shaped chain stitch loops. This stitch is ideally worked from right to left. Once you are familiar with the logic, you can work from left to right as well.
I will be working on a single stitch line. The stitches will fall on either side of this stitch line, except the first one.
