Thanks folks. I wish I had started learning to do knots before the arthritis got to my hands but I guess we do what we can.
As for patterns, I have several books that are OK at best but the instructional videos on YouTube are great, especially since I can pause them while I wring the confusion out of my brain. (my calculations are my brain is about 70% confusion, 20% uncertainty, and 10% some unidentified brown substance.)
I also learned on YouTube that you can tighten a paracord wrap by pouring boiling water on it once it's finished. I haven't tried it yet but am anxious to see the results. By the way, the stick with the snakes head is my first ever walking stick. It is a Hickory sapling that I dug up on my grandfathers farm about 40 years ago. Still strong and very light. I wish I had a source for more like it.
