Step 1

The square knot is made from 4 cords. Let us number them 1 to 4 from left to right as shown in diagram 1. 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 knot.

Step 2

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 in diagram 2.

Step 3

Now 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 in diagram 3.

Step 4

This completes the top half of the square knot and the cords should be pulled tight as shown in diagram 4 before tying the bottom half which is essentially a mirror image of the top half.

Step 5

Start the bottom half by bringing the working cord 4 back to the right, behind the filler cords 2 and 3 and on front of the working cord 1 as shown in diagram 5.

Step 6

Next pass working cord 1 back to the left, in front of the filler cords 2 and 3 and back through the loop so it passes behind the working cord 4 as shown in diagram 6.

Step 7

Now pull this bottom half tight in a similar way to the top half and adjust as necessary. This completes a left-handed square knot.

Step 8

Repeat steps 2 to 7 twice more until you have 3 square knots in a line as shown in diagram 8.

Step 9

To make the berry knot we will curl the 3 square knots up by passing the filler cords from the bottom up and through the filler cords above the 3 knots. The green oval on the diagram 9 shows the target area where we will pass the filler cords.

When the cords above the berry knot you want to make are already knotted, then you may need to use a hook, like a large crochet hook, to help you pull the cords through (see later)

Step 10

Pass the 2 filler cords from below the 3 square knots up in front of the knots and through the target area between the filler cords above the 3 square knots.

Step 11

Pull all of the 2 filler cords through and allow them to drop behind the 3 square knots.

As you pull the filler cords through the 3 square knots will begin to curl up.

Step 12

Pull the filler cords down behind the newly formed berry knot.

Step 13

Now take the working cords again, that have not really moved at all, and tie another half square knot below the berry knot.

Step 14

Pull this half square knot tight. You may need to manipulate the berry a little to ensure you get the working cords tied neatly below the berry.

Step 15

Complete the square knot below the berry by tying the bottom half.

Step 16

And pull tight.This completes the berry knot.

As this knot is 3-dimensional see the side and rear view below.
