The Ibo knot is the traditional Japanese knot used to tie bamboo fencing together. This knot bears some resemblance to a modern square knot but offers a cleaner appearance. Use black palm fibre string when tying bamboo fencing together, as this is the traditional string used in Japan and will add an extra touch of authenticity to your project.
Wet the string. It is always best to wet any natural twine before using it because the twine will tighten as it dries, making an even tighter knot.
Form a figure 8 with the string going from left to right, crossing the back, front and back of the two bamboo pieces.
Loop the left side piece over the right side piece.
Loop the right side piece over the left side piece and pull the piece through the loop. Pull the knot as tight as you can.
