I have to check, I think the knots are not true French knots but are called colonial knots.

Later..

Okay, I looked up my stitches! What I did for knots is some kind of modified French knot. Not really either of the two types of knots.

And my stem stitch is... something like that.

I know, it still looks sad, but spring is here! Have been enjoying sitting outside every now and then. Have started cleaning up the yard.
