To make macramé knots, begin with the basic knots such as the half knots or square knots, then prolong to the desired length. To make the square knots, tie two cords on a ring, and begin with either the left or the right cord to obtain the corresponding knot.
To make left square macramé knots, secure two cords to a ring, and mentally number the resulting cords one to four from left to right. Take the first cord over the central cords, but under the fourth cord. Pass the fourth cord under the central cords, but over the hole formed by the first cord. Pass the first cord under the central cords, and over the fourth cord. Take the fourth cord over the central cords, then under the first cord through the resulting hole, and repeat the process.
The mirror square knot, or right square knot, reproduces the left square knot in the opposite direction. Tie the two cords around a ring, and pass the right cord over the central cords, but under the left cord. Pass the first cord under the central cords, but over the fourth cord. Repeat these steps until you obtain the required length. Stitching both the left and right square knots becomes helpful when designing symmetrical edges of a stitch.
