It's referred to as Gravenmoersche appears to be a half stitch ground that has a little different orientation than a regular half stitch ground. Honestly the variation seemed almost indistinguishable but I gave it a go. And then took it out and gave it another go. And so on. I finally admitted defeat and finished the piece with the old standard.
Even if I couldn't do the proper stitch, that would have looked like this
It's still a lovely pattern.
Fortunately, that miss was followed by a lesson on something I've long wanted to learn - how to start and end a piece with a border that runs all the way round. There's a fan I'm going to do one day that needs to start like this.
On this technique the diagrams were very clear indeed and I'm so happy to have this reference point for the day I begin The Fan.
This lesson had a whole array of variations for the ground sections that could so easily be substituted for basic rose ground and add a little bit of fancy to any pattern. Trails, border, grounds. This one had a bit of everything!
And what does tomorrow hold? Perhaps the warping of a loom? Perhaps the start of a new lace? Time, as they say, will tell.
For now I'm happy with whatever comes.
