I love this resource. So many useful knots. Particularly I like the lanyard / friendship knot [1] and the midshipman's hitch (adjustable slip hitch) [2], the latter of which is probably about 90% of the knots that I tie. Honorable mention to the constrictor knot for attaching to large cylinders [3].
