I've been costuming most of my life, most of my SCA focus has been of the North Rhine.
While my focus is on a small region and about 150 years it is all encompassing and embraces an understanding of laws, life, and how clothing fits in that.
I have also experimented with patterning across the Northern Renaissance and have developed a set of patterns that can be used both to help recognise garment structure in portraits and be used to make those garments. I keep revising this for ease of use but hope to have it presented in full later this year.
