Ring hitch
The common and useful ring hitch, done using only one hand.
Start with the center of the rope draped over the thumb.
Press the thumb flush against the hand. This will pinch the rope between your thumb and the edge of your palm.
Dip your hand down, passing the fingertips behind the line you are pinching with your thumb.
Pick up the far line, pinching it between your index and middle fingers.
Start bringing your hand back up. You will see that a loop has formed around your thumb.
While bringing your hand back up, flip it away from you slightly so that the line will go over the outside edge of your index finger.
Flip your hand back down. A second loop will now be formed around your index finger.
Touch the tip of your index finger to the tip of your thumb.
Using your other fingers, slip the loop on your index finger over onto your thumb.
