Based on a book of woodcuts from master Koebel. Aiming for 1530s-1550s. The wams being wool and not leather is somewhat debatable, but not an inaccuracy in my opinion.
The fabric is a well felted light melton.
A lot of fun to make, but entirely dependent on getting the right felted wool like this melton. I even wrote a free guide for mine, but can't link it directly because of the Reddit self promotion policy.
The drafting was done using the wrap method and a lot of intuitive adjustments, as modern patterning doesn't work when it comes to pre-modern clothing.
I am an armorer and this is the kit I made. Photos from Plataea and the helmet update since then.
We only have two renfaires in my country, I am taking them to the better one.
