How to Tie a Sheet Bend
The sheet bend and its popular variations, the double and triple sheet bend, is a critical knot for anyone to know. You may choose to tie a sheet bend over a square knot because of its ability to join two ropes of equal OR unequal diameter. In fact, the sheet bend can join two items that aren’t even ropes, like sheets (hence the name).
Here are the fast facts you need to know to tie and use a sheet bend properly. The standard of proficiency for tying a sheet bend is: In any environment, given a sling rope, while blindfolded (or in complete darkness), tie a double sheet bend within 30 seconds or less, ensuring that each pigtail is no shorter than a fist and no longer than a fist with thumb extended (4-6 inches).
Sheet Bend Use
The sheet bend is a Class 1 (End of the rope) knot that is used for joining two ropes of equal or unequal diameters. The double sheet bend is very secure and is the standard sheet bend variation for life safety systems. The single sheet bend can potentially slip when used on ropes, particularly new ones.

Tying a Sheet Bend Step-by-Step Breakdown
Step 1
Start with a bight in one hand and a section of pigtail in the other
Step 2
Pass the pigtail through the bight
Step 3
Wrap the free running end around the bight forming an opening
Step 4
Pass the running end through the newly formed opening. If you set and dress the knot now, you will have a (single) sheet bend. Continue to step 5 for a (double) sheet bend, which is preferred.
Step 5
Wrap the running end around the bight a second time.
Step 6
Pass the running end through the opening from step 4 between the last pass and the end of the bight.
Step 7
Set and dress your (double) sheet bend! Note: If you require even more security, you could pass the running end through the opening a third time to create a (triple) sheet bend.
