TAST Pistil stitch
It seems to me that I have done this stitch. At any rate I have done a million french knots so I am pretty comfortable with this stitch. I started by taking a few stitches and then realized that this stitch reminded me of fireworks. That is what I tried to portray here. I probably should have done it on a black ground though. Thanks to Sharon B at http://pintangle.com/ for the instructions.
