I just wanted to learn a few knots to join some bamboo poles together to make a trellis. On YouTube, I found what I needed. It was interesting to see who posted knot tying videos. Boy scouts, preppers, survivalists, and artists were among the knot enthusiasts.
I used a round lashing to join two bamboo poles together to make a longer pole.
I used a shear lashing to join the top of the trellis together.
I really like this Japanese square lashing. This one was good for a 90 degree join between poles.
