Chevron stitch and half Chevron are both a variety of Herringbone stitch since both are worked with a similar hand motion.
Work from left to right on two imaginary parallel lines. To keep the width of the stitches even on fabric that is not an even weave guide-lines can be marked on the fabric using one of the fade out or water dissolvable pens available.
Step 1
Step2
Bring the thread out through the fabric on the left of the lower imaginary line. Insert the needle a little to the right on the same line, and with the needle emerging at the middle make a small stitch.
Take the needle up and insert on the upper imaginary line and make a small stitch pointing the needle downward and have the thread looped under the needle.
Take the needle through the fabric. Move diagonally across to the right and insert on the lower imaginary line, bringing the needle out a little to the left, and pull the needle through the fabric.
step 3
Still working on the bottom imaginary line take the needle across to the right and insert, bringing it once again out in the middle. Work this way along the row.
step 4
You can work this stitch on plain and even weave fabric in most types of embroidery thread to create useful border or outline stitch, which unlike Chevron stitch follows curves well.
It can also be worked row on row to make a filling stitch. Since this creates a patterned grid isolated stitches such as French knot, Colonial knot or a bead can be placed in the centre to further decorate the filling. The lower edge of the stitch looks and is exactly the same as chevron stitch.
The top spine of Half chevron stitch or the whole band of half chevron can be used to couch heavier threads to a piece of work.
