I've uploaded some progress pictures of the St Martin's panel to Flickr. The above picture shows the current state of things. I've finished the color fill stitching and I'm working on the outlining.
The next thing that I have to think about is painting on the faces. Lady Sabine Berard has generously posted some
pictures from the Cloisters at the NY Met. In them, she has a great close up of a painted face from a piece that came out of the same convent:
picture. In this particular piece the face is done in "encroaching Gobelin stitch" and painted on, but on the St Martin's panel they just used a regular brick stitch as the foundation.
Unfortunately, I haven't read much on what kind of paint was used for the face. From scribe's guild I know that gouache paint is a good modern equivalent for scroll work, but I'm not sure for painting on embroidery. I'm still looking for sources though, so if anybody knows anything, I would be most grateful.
