This is the 25th week stitch of the stitch challenge TAST2010 by Sharon.B.
The next set of variations-
4a. I tried curving the vandyke stitches[a small secret, I had to go through the fabric at some places to maintain the curve]
4b. A row of three small stitches and one long stitch.
4c. Vandyke stitches are of varying heights.
If beads are added In these three variations, they’ll look great.

vandyke st-4a,4b,4c

A few more variations to go.
