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.
Practice. I had a friend that was in her residency living with 2 other baby doctors.
They always had a pile of string on the table in front of the TV and would practice tying surgical knots (whatever exactly those are, IDK). They wanted to develop the muscle memory so they could tie them without looking.
