This textile is 23 x 20 cm, linen embroidered in dark blue silk for the double running stitch, with light green and brown silk in the encroaching gobelin stitch. It is currently in the Ashmolean Museum.
I personally think that the stitch used to fill in the green and brown is gobelin, while the Museum calls it a “slanted counted filling stitch”. Here is a detail of one of the green sections- I am happy to be corrected.

Let me know how the embroidery goes!
