The IRCC shirt is almost complete. I have finished the blackworking for both the cuffs and for the collar. I did all of the blackwork using backstitching as it would have been done in Italy during the mid 16th century. Here are some photos of the black work.

I did all of the blackworking on a hoop and then cut the pieces to the proper size when complete. I have since assembled one cuff completely, but have not yet photographed it. I hope to have the entire shirt completed in the next couple days. One remaining detail I haven't decided on though, is the closures for the neck. I plan on using a braded line, but haven't decided if I will use solid white (as I did for the cuffs) or a combination of black and white as I have seen on some portraits. We'll have to see what sort of mood I'm in in the next couple days when I braid it.
