I just read a
Puttees Tying Guide, and it's very informative.
Jethroskulls wraps look really good, and in my opinion, I would go with canvas strips, that was my go to thought.
I honestly don't know how you would use the bandages. If you glued and painted them, that would make a short of hard shell, that you'd have to cut from top down, and figure out how to make it look all 1 piece, and if you used bandages, in my experience as a boy scout, they would be hard to weather properly, and they might be too thick to give the proper effect. If you use regular canvas, or some other more durable fabric, it would be easier to use and weather.
