It is best to use this where backstitch is to be added on the diagonal rather than a three quarter stitch.

Work a long vertical stitch from 1 to 2 over four threads tying it down with a small horizontal stitch over one thread at 3 as shown. Work a second vertical stitch, this time tying it down at 4. The central two stitches are worked in the same way with the smaller stitches inside the first pair as shown.
Rococo stitch is a variation where six vertical threads are worked, three on either side.

This can be used to cover large areas but is unsuitable for a upholstery since it uses long stitches. Long threads are laid diagonally across the area only entering the fabric at both ends. These stitches must cross thread intersections over their whole length. The laid threads are then crossed at right angles by groups of three diagonal stitches arranged as shown.

Buttonhole stitches are worked first on one side and then the other along a straight line. Also known as alternating button hole stitch.

First work a central vertical stitch over twelve threads and then make the lower arrowhead shape with four stitches. Tie down the long stitch with a horizontal stitch over two threads and complete with the four upper arrowhead stitches. The following stitches interlock as shown to cover the fabric.
