Two half hitches

For greater strength and resistance to slipping than is offered by the half hitch, use two half

hitches rather than one.

Start by passing the rope around the post to which you are hitching it (1). Then pass the working
end around the loaded end, and feed it between the post and the loop to form the hitch (2).
Repeat the process by passing the working end around the loaded end again and feeding it through

to make a second half hitch (3). Pull the loaded end to tighten the knot (4). The hitches should
slide to tighten around the post.
