Draw two parallel guidelines and start midway between then, slightly in from the right hand edge.  Work a small diagonal stitch from top left to bottom right (your stitch should end on the bottom guideline).

Bring the needle up on the bottom guideline, a short distance to the left and take the needle down in the same hole where the first diagonal stitch emerged. This completes the first V-shape.

Come up midway between the guidelines to the left of the tip of the first V-shape (the same distance as the width of the first V-shape), and work another diagonal stitch.

Bring up the needle to the left, and take the needle down to make the second V-shape.

Continue in the same way to create the foundation line of V-shapes.

Starting a new thread, bring the needle up one thread above where the bottom V-shape foundation ended. Take your thread over the V-shape, then slide the needle under the right side of the V-shape, from right to left, keeping your working thread to the outside of the border.  Do not pierce the fabric.

Chevron stitch

Move onto the top V-shape and pass the needle under the diagonal stitch on the left, again working from right to left but this time keep your working thread to the centre of the border.

Now go under the diagonal stitch on the right, again working from right to left, this time keeping your working thread to the outside of the border.

Move onto the next bottom V-shape. Pass the needle under the diagonal stitch on the left, working right to left, keeping your working thread to the centre of the border.

Continue in the same manner to work a row of chevron stitches over the foundation without piercing the fabric.
