Herringbone stitch is another I like, possibly because of it's resemblance to cross stitch.
I used a line of it to couch down the edge of the lace, and then put in a french knot in each of the spaces of the little cups.
On this hexagon, I did two rows of double herringbone in a thicker thread.
I am now all caught up, unless I get another flash of inspiration and add something else, otherwise, I am waiting for next weeks stitch to be revealed.
