The technique I used is called Speckling, which became popular in England during the Elizabethan period . Basically, the motif is outlined in outline stitch, and then shading is added using small straight stitches and seed stitches.
If you didn't catch my post about how this scarf was made when I posted it, you can read a more detailed account - just click on "Blue & White Rose Scarf" under Projects on the right hand bar. It's filed under June.
