Knotted Satin Stitch
It didn't take long to learn this stitch, but it was a struggle to get it right. These Satin Stitches need to be crowded, and the shorter the leg, the nicer they behave.
This row of triangular stitches was a pleasure to work, meditative and easy, and gave a very pleasing result. I like both the pulled-tight version that opens holes in the fabric
and the version where the thread stands out.

Mountmellick Stitch
The main stitch in the Irish Mountmellick embroidery style is a favorite from the past and was nice to use once again, here in colour and on thin red fabric.
Norwich Stitch
This is a Canvas stitch and I learned the hard way that such stitches really should be worked on CANVAS and not on any limp fabric. I also learned that if you mark plain fabric and choose your thread well you can get stunning result.

Open Chain Stitch
This version of Chain stitch was easy and enjoyable to play with, and I am very grateful to CrazyQstitcher for suggesting tying the rungs of the ladder together into bunches.
Homework:
Put SSS stitches 11 - 15 to good use on yet another Sunbonnet Sue design.
Now do you remember the name of this stitch? What kind of design of Sunbonnet Sue is it, do you think?
