I believe knot-tying would be a great, life-long skill to have, especially being able to know which knots work best for different situations, like when the rope is thick and not very flexible or bendable.
I have lots of nylon rope and fishing line of various diameters, but don’t know where to begin and/or the best way to get started. My goal is to make this a long-term hobby and spend 1-2 hours per week improving my knot-tying knowledge, skill, and speed.


Same. I’ve learned from trying to follow videos that knots which look easy might be a reflection of the person’s skill (at making them seem easy) and maybe they have practiced tying that knot 5000 times in their lifetime. Some knots look simple but are deceptively complicated. 😣
