About this knot
This is one of the most common knots used in macrame and is very easy to learn. With practice you will master a technique and the muscle memory to enable you to tie them quickly without thinking too much, very much like knitting.
How to tie this knot
The square knot is made from 4 cords. Let us number them 1 to 4 from left to right as shown below. Cords 1 and 4 are the working cords, and the cords 2 and 3 are filler cords and just pass through the middle of the square knots.
Begin by passing the working cord 4 to the left behind the filler cords 2 and 3 and in front of the working cord 1 as shown below.
Next take the working cord 1 and pass it to the right in front of the filler cords and through the loop made by cord 4 so that it passes behind cord 4 as shown below.
This completes the top half of the square knot, and the cords should be pulled tight as shown below before tying the bottom half which is essentially a mirror image of the top half.
Start the bottom half by bringing the working cord 4 back to the right, behind of the filler cords 2 and 3 and in front of the working cord 1 as shown below.
Next pass working cord 1 back to the left, in front of the filler cords 2 and 3 back through the loop made by working cord 4 so it passes behind the working cord 4 as shown below.
Now pull this bottom half tight in a similar way to the top half and adjust, as necessary. This completes the left-handed square knot.
Many square knots in a row lie flat and form the pattern shown in the diagram below.
