Being long overdue to post here again I would like to rectify that with posting a link to my handout made for Aarnimetsä Academy this past November. I led a workshop in Elizabethan metal thread embroidery and brought fabric and thread for gentles to have a go at a few stitches.
The handout can be found off my website's Embroidery pages.
It is based on my study of one particular extant coif (which, until March 1 2011, can be taken out and examined at the Victoria & Albert museum in London). For a few of the stitches I have used diagrams from the Plimoth Plantation Embroidery Blog, and some of the diagrams Baroness Felicitas of Gotvik helped me to create.
