Hi folks,
a friend of mine is doing some slight restoration work on my new tatami-do. During his work, the do reveals his construction. Surprisingly, only the mail has a backing of dark blue fabric strips Than, as usual, followed from a layer of linen (or hemp?) and finally covered with dyed leather.
Furthermore, every single plate is marked on the backside with characters in red lacquer. I assume, it helps the katchu-shi to determine the position of a plate in the whole arrangement.
What you don`t can see in the pics is, that the front and the back of the dou are hinged, just like a "normal" dou. All in all, not that simple and cheap as tatami armors always postulated.
Note, that the kusazuri for front and back are different
