Step 2: Tying on footrests
The first thing to do is to lay the pole on the ground, and sandwich it tightly between the two footrest boards, as in the first photo. Place the footrest boards so that they extend about 1.5" below the septa, and then go up from there. Then tie the sandwich together very tightly with a very generous amount of twine, with the center of the twine about 2.5" from the bottom end of the footrest boards.
Tie off the twine.
The photo on this page and the photos on the next are from a re-enactment after the stilts were assembled. Since I am submitting this to the sustainability contest, I didn't want to waste any bamboo, wood or string for making photos afterwards, so the pieces aren't quite the right length. I also notice that the septum is in the wrong place, too--sorry.
