The variations of siennese stitch from the stitch challenge-TAST2010.
The details-
9a-The vertical version of siennese stitch, I tried placing one stitch on top of the other, and the top stitch is smaller than the bottom stitch here.
9b- Similar idea of 9a,but the stitches are of same size.
9c- Here the stitches are made in a curved line.
