How to tie a Sheet Bend
orm a loop with one end of a length of rope. Take the end of the second length of rope underneath and then up through the loop.
Pass the end of the rope that you are working with (the working end) around the back of the loop. Take care that you go around the short end of the loop first and then behind the loop.
Now take the working end over the front of the loop (over the long end of the loop) and tuck it inside itself.
Now hold the loop (green) and pull the standing end of the second length (red. Recall that standing end is the long end that you are not moving around, the bit that goes off to the tree or whatever). This should lock the knot in place.
If you really want the bend to be secure then seize the two ends together.

Proceed as above but do not tighten the knot at the end. Now pass the working end (red rope) around the loop.
Once you have gone around the loop again then tuck it underneath itself.
Pull the knot tight to secure it.
