In this tutorial, I will show how you can make the square knot also called the box knot using plastic wire. This knot is the most commonly used knot in basket weaving.
You will need two pieces of wire. Fold them and make loops like shown below.
Place one loop around the other.
Fold up so the wire looks like the English letter N.
Now weave the yellow wire as shown below.
Knot is done.
One method of joining two box knots (1 and 2) is by placing them next to each other and making one knot above (3) and another knot below (4).
