Take the working end
3 across, then behind, the
standing part and pass it
through the knot to tie
a half-hitch.

Now make an identical
4 half-hitch.

Pull on both rope parts to

Add an extra round turn at
step 2 to make two round turns and
two half-hitches, and you will have a
great knot for fastening rope to a
strong tree limb to make a swing .
