hy,
just did the 3 Maps from the Klear Games PC-Adaptation of this as real game board. Just print them on A4 Paper without borders to keep the hexes in scale. This is the Uchinoke map as you can see here:http://www.boardgamegeek.com/image/281458
I will print mine on a A3 Printer and will cut away everything that does not look like Samurai :D
Have fun!
