Ok, to work Raised Herringbone Stitch first mark a leaf or petal shape on your fabric with a fabric marker pen. Now using a blunt needle throughout bring your needle up at 1 (the bottom of your leaf), down at 2 and up at 3. Pass your needle from right to left through the vertical stitch without piercing the fabric and then insert your needle at 4 and up at 5 to begin again. Repeat this sequence until your entire shape is filled. This really does create a lovely textured leaf or petal shape.
