Pintangle site posted the Buttonhole wheel cup stitch I thought it'd fill them in nicely.
Crossed & Plaited Feather Stitch. I'd done Feather stitches before oodles of times but not straight feather or crossed feather. I didn't do the Plaited Feather Stitch though.
Portuguese Border Stitch.
detailed tutorial on how to make one and I'll definitely try another.
Have a lovely, beautiful and fine, fine day :)
