The Sheet Bend is used to join two ropes of different thick nesses together. The smaller diameter rope should pass around the larger one. This knot can be used to tie a rope to an eye for light loads. The knot is very fast to tie and when slipped, is on of the easiest to work with.
To Tie a Sheet Bend:
Form a bight (with the larger diameter rope).
Insert the second rope under and then over the end of the first rope.
Take the end of the second rope and bring it under the bight.
Bring the end over the bight, putting it under its own standing part.
