I’m enjoying working with this spiral trellis stitch.  I tried another example:

The paisley shape is outlined in 3 rows of trellis stitch.  There’s  a round spiral trellis inside the shape, and the inside is filled in with some random French knots.  This is all done with a variegated no. 5 perle.

On an angled view, you can see the height of the paisley shape a bit better:

I like how this stands out from the background.  But lesson learned – filling in the inside after having first built up the edge was not smart.  I should have done this in reverse.  After outlining the shape in backstitch, I should have first stitched the inside circle, then done the edge.
