Related to this question on meta Why is this question closed as duplicate? what are the lines for duplication where the question isn't exactly the same, but the reference duplicate contains the answer as well as more comprehensive information? I'm referring specifically to the question of knots.
We have individual knot questions:
How do I tie a Prusik knot?
How do I tie a double fisherman's knot?
How do I tie a bowline knot?
Versus a more comprehensive knot answer, What are good knots to know for camping and backpacking?
