Step By Step:
- Take two pieces of line, one in each hand
- Make an X with the two pieces
- Take the line that was originally in your right hand and wrap it under the line in your left hand
- Both lines should be intertwined.
- Take the end of the line that is in your left hand and wrap it over and under the end of the other line
- Pull the two ends of the line tight to form the square knot
