Now, I'm not actually cross-stitching, per se; I just needed a shape generated so I'd know what shape I was stitching. (Um, that was clear as mud. Hopefully you followed along anyway.) So, I backstitched the whole thing, and started filling in the backstitched area with Smyrna crosses, cross stitches and French Knots.
I then chose a fill stitch for the center background:
And then finished it up. I love the look of the French knot "flowers", and how the design gets warmer closer to the center. I think it came out great!
