The device is made of wool felt. The design elements are cut out and sewn on. Then embellishment is added with embroidery. I initially used tapestry wool, but the result was too thick and bulky so I unpicked it and used some fine embroidery wool. The ermines were made from large seed beads and drop beads, and the small details were sewn with DMC cotton floss. Some metallic thread was couched down, and then I added another piece onto the back to make the shape more solid.
The completed piece will be added to the Baronial device banner.
